Normal Feline Social Behavior
... This interspecific use of purrs may be a consequence of captive cheetahs' developmental backgrounds, in which human hand-rearing is common practice [71][72][73]. Purrs are often emitted in association with positive social interactions and bonding at juvenile stages in felid species, such as in the domestic cat that purrs as a form of contentment or request for care from the mother [74] or emits purrs redirected to humans to solicit care [75][76][77]. Hence, the purring of Early-Orphaned cheetahs toward humans may reflect social affiliation with humans as a consequence of the parental bond being replaced/supplemented by their human caretakers and/or a form of neoteny resulting from early deprivation from their conspecific primary adult model [6]. ...
It has been argued that domestication explains the ability of domestic animals to use human cues, but similar abilities exist in wild animals repeatedly exposed to humans. Little is known on the importance of the developmental stage of this exposure for developing such abilities. Orphancy and subsequent hand-rearing constitute a quasi-experimental situation for investigating this question. Cheetahs (Acinonyx jubatus) are interesting as they present a two-step development, spending their first two months of life in a den with occasional visits from the mother, and then accompanying their mother outdoors. Mother loss may occur at any of these stages, and the orphaned cheetahs are then taken under human care. We tested the importance of the stage of development on their long-term perception of humans by comparing the reactions of adult wild-born cheetahs, orphaned at “den-age” (Early-Orphaned, 0–2 months) or at a later stage (Late-Orphaned, 2–6 months), to motionless humans (familiar vs. unfamiliar). The results showed that Early-Orphaned, but not Late-Orphaned cheetahs, produced affiliative calls (purrs) towards humans and discriminated familiar and unfamiliar humans. Taken together, these results suggest that the timing in which an emotional bond is created with the primary caregiver (humans in the case of Early-Orphaned cheetahs and the mother in the case of Late-Orphaned cheetahs) is crucial in determining the reaction towards the species of the early caregiver throughout life.
... From studies outside the household context, it is known that cats can demonstrate territorial as well as cooperative behaviours to conspecifics, and thus have flexibility in their social organisation (Bradshaw, 2016;Vitale, 2023). However, the intraspecific social behaviours and dynamics can vary enormously between multicat households. ...
Domestic cats are increasingly popular as companion animals, but behavioural problems are often reported, especially in multicat households. Social tension is a common stressor, so understanding intercat interactions and their dynamics is crucial. Nevertheless, direct research in the home setting is rare. As caregivers witness their cats’ behaviour on a daily basis, they are a potentially important source of information, but might be unreliable and subject to bias. This study examined the reliability of caregiver reporting by comparing survey answers with behaviours observed in home videos collected after the survey was completed. The occurrence of five cat-cat interactions (head rubbing, allogrooming, sleeping in physical contact with each other, tail up greetings and social play) was examined in 42 two-cat households using 210 survey answers and 775 videos. The percentage of false negative survey responses for behaviours observed in the videos was conservatively estimated (cFN) at 8%, with 22.9% of the negative answers being falsely negative (FOR – False Omission Rate) and 77.1% truly negative (NPV – Negative Predictive Value). Broad false negatives (bFN), which included uncertain responses as negative reports, were 9.5% of the survey responses with a FOR of 75% and NPV of 25% in this context. Highest values were obtained for head rubbing (cFN: 10.5%, bFN: 14.3%) and allogrooming (cFN: 9.8%; bFN: 11.9%). When focusing on individual cat caregivers, 14 out of 42 caregivers (33.3%) failed to reliably report the occurrence of at least one of the surveyed cat-cat interactions. For interactions that were seen on camera, 23.8% of caregivers (10/42) responded that their cats did not show these interactions and 9.5% (4/42) reported uncertainty about whether it ever occurred. These results should be considered a lower estimate of the magnitude of errors (false negatives) in caregiver reports, and their implications need to be considered in both research that depends on caregiver report, and clinical assessments within behavioural medicine. Many cat-cat interactions, and in particular head rubbing and allogrooming, will be underreported when relying exclusively on caregiver reporting.
Lately, there has been a growing interest in studying domestic cat facial signals, but most of this research has centered on signals produced during human-cat interactions or pain. The available research on intraspecific facial signaling with domesticated cats has largely focused on non-affiliative social interactions. However, the transition to intraspecific sociality through domestication could have resulted in a greater reliance on affiliative facial signals that aid with social bonding. Our study aimed to document the various facial signals that cats produce during affiliative and non-affiliative intraspecific interactions. Given the close relationship between the physical form and social function of mammalian facial signals, we predicted that affiliative and non-affiliative facial signals would have noticeable differences in their physical morphology. We observed the behavior of 53 adult domestic shorthair cats at CatCafé Lounge in Los Angeles, CA. Using Facial Action Coding Systems designed for cats, we compared the complexity and compositionality of facial signals produced in affiliative and non-affiliative contexts. To measure complexity and compositionality, we examined the number and types of facial muscle movements (AUs) observed in each signal. We found that compositionality, rather than complexity, was significantly associated with the social function of intraspecific facial signals. Our findings indicate that domestication likely had a significant impact on the development of intraspecific facial signaling repertoires in cats.
Despite the diversity of social situations in which cats live, the degree to which free-ranging cats (FRCs) are social is still debated. The aim of this review is to explore the literature on the social behavior of FRCs. A search of two major databases revealed that observations of intraspecies and interspecies social interactions have been conducted. The intraspecific social dynamics of FRCs differ based on group of cats surveyed. Some groups display strong social bonds and preferential affiliations, while other groups are more loosely associated and display little to no social interaction. Factors impacting FRC conspecific interactions include cat body size, cat social rank, cat individuality, cat age, relationship to conspecific (kin/familiar), cat sex, level of human caretaking, presence of food, the health of the individual, or sexual status of conspecifics. Interspecies interactions also occur with humans and wildlife. The human’s sex and the weather conditions on the day of interaction have been shown to impact FRC social behavior. Interactions with wildlife were strongly linked to the timing of cat feeding events. These findings support the idea that FRCs are “social generalists” who display flexibility in their social behavior. The social lives of FRCs exist, are complex, and deserve further study.
The chapter is about affiliative behaviours, factors that influence affiliative behaviours, and benefits of affiliative behaviours
Standardized ethograms offer many practical benefits to behavioral researchers, and several examples exist today for various species and taxa. Despite historic evidence that suggests the family Felidae share similar behavioral repertoires, no standardized ethogram providing comprehensive behavioral definitions exists. In order to create a working ethogram for the Felidae, we conducted a thorough literature review of published articles and books containing behavioral definitions designed for felid species. A total of 95 documents qualified for inclusion, and each was evaluated to identify the terminology used in its behavioral definitions, along with any categorization implemented. The articles included the behaviors of 30 species and 40 subspecies of felids, with the most frequent single study species being the domestic cat (Felis catus), followed by several “big cats”. The results were organized into the following mutually exclusive groups for comparison: domestic cat studies, big cat studies, and small cat studies excluding domestic cats (i.e. small exotic cats). Systematic review of definitions confirmed that researchers tend to define felid behavior in similar manners, although some divergence was found between the inclusion of behaviors in domestic and exotic (non-domestic) cat studies. Information from the literature review was used to create a standardized, universal ethogram for use in future felid behavioral studies. The final ethogram suggests the use of “base behaviors” which can be altered using pre-defined modifiers in order to accommodate the requirements of individual studies while retaining consistent terminology. Common behavioral categories are also defined, and suggestions of behaviors that qualify within each category are presented to further assist researchers when developing their study. The ethogram was designed to be user-friendly with clear definitions for each behavior, which should be coherent to a diverse range of observers. We anticipate that use of this ethogram will save researchers time and effort in creating behavioral definitions for their study, while also assisting in unifying felid behavioral research.
Despite widespread interest in inter-specific communication, few studies have examined the abilities of companion animals to communicate with humans in what has become their natural environment — the human home [1

]. Here we report how domestic cats make subtle use of one of their most characteristic vocalisations — purring — to solicit food from their human hosts, apparently exploiting sensory biases that humans have for providing care. When humans were played purrs recorded while cats were actively seeking food at equal amplitude to purrs recorded in non-solicitation contexts, even individuals with no experience of owning cats judged the ‘solicitation’ purrs to be more urgent and less pleasant. Embedded within the naturally low-pitched purr, we found a high frequency voiced component, reminiscent of a cry or meow, that was crucial in determining urgency and pleasantness ratings. Moreover, when we re-synthesised solicitation purrs to remove only the voiced component, paired presentations revealed that these purrs were perceived as being significantly less urgent. We discuss how the structure of solicitation purrs may be exploiting an inherent mammalian sensitivity to acoustic cues relevant in the context of nurturing offspring.
Research into cat behavior has gained more attention in recent years. As one of the world’s most popular companion animals, work in this field has potential to have wide-reaching benefits. Cats living in shelters are posed with distinct welfare concerns. Shelter cat welfare can be increased through use of environmental enrichment to promote natural behaviors. This review focuses on relevant literature published to date on shelter cat enrichment. Several key areas of research were identified. These included sensory enrichment, feeding enrichment, physical enrichment, social enrichment, and assessments to determine cat preference for enrichment stimuli. Existing studies have examined the efficacy of enrichment to promote species-specific behaviors and to reduce stress in shelter cats. Studies have also explored housing conditions for shelter cats such as cage size, communal housing, or the general quality of the environment. Applications of this information are discussed in order to promote natural cat behavior and find ways to increase the welfare of shelter cats. A review of the literature highlights the importance of supplying novel items in shelter environments, providing a rotation of individually preferred items, the use of human social interaction as a way to increase interactive behaviors in shelter cats, and the importance of considering potentially aversive impacts of enrichment under certain situations.
The Secure Base Effect (SBE) refers to a human or non-human animal’s ability to use the presence of a bonded caretaker, or other familiar stimulus, as a source of comfort that facilitates stress reduction and exploration in novel or stressful contexts. Recent research has shown that some pet domestic cats (Felis catus) display SBE in the presence of their human owner, a finding that could be utilized to improve cat welfare. In applied settings, cat owners are often encouraged to leave behind items holding their scent when leaving their cat in a novel location (e.g. boarding facility), so that these items can be provided to the cat if they show signs of separation distress. While this practice has not be studied scientifically in cats, scent objects have been found to produce SBE in human research under similar conditions. Olfaction is thought to play an important role in the social behavior of domesticated cats, even in early life, as exposure to nest scent has been found to reduce stress in kittens. Thus, the possibility that owner scent might be sufficient to elicit SBE in cats is an important empirical question with applied implications. In the current study we asked whether owner scent would reduce cat anxiety when in an unfamiliar environment, and to what extent this might be related to whether the cat showed evidence of using their owner as a Secure Base. Forty-two adult cats underwent a counterbalanced Secure Base Test that examined the cat’s behavior with the owner present, without the owner present, and with a scent object present. On average, cats displayed a lower frequency of stress-related behaviors when the owner was present, providing support for the presence of SBE. However, this effect was not seen when the cat was alone with the scent object. The results of this research can be used to deepen our understanding of feline social behavior and welfare. These findings also highlight the importance of using evidence based practices to address cat anxiety in applied settings.
Worldwide, domestic cats (Felis silvestris catus) outnumber domestic dogs (Canis familiaris). Despite cats’ success in human environments, dog social cognition has received considerably more scientific attention over the last several decades 1, 2, 3. A key aspect of what has been said to make dogs unique is their proclivity for forming attachment bonds, including secure attachments to humans 1, 3, which could provide scaffolding for the development of human-like socio-cognitive abilities and contribute to success in human environments [3]. Cats, like dogs, can be found living in social groups or solitarily, depending on early developmental factors, resource distribution, and lifetime experiences such as human interaction 1, 2, 4. Despite fewer studies, research suggests we may be underestimating cats’ socio-cognitive abilities [2]. Here we report evidence, using behavioral criteria established in the human infant literature 5, 6, that cats display distinct attachment styles toward human caregivers. Evidence that cats share social traits once attributed to dogs and humans alone would suggest that broader non-canine-specific mechanisms may be needed to explain cross-species attachment and socio-cognitive abilities.
This study investigates domestic cat meows in different contexts and mental states. Measures of fundamental frequency (f0) and duration as well as f0 contours of 780 meows from 40 cats were analysed. We found significant effects of recording context and of mental state on f0 and duration. Moreover, positive (e.g. affiliative) contexts and mental states tended to have rising f0 contours while meows produced in negative (e.g. stressed) contexts and mental states had predominantly falling f0 contours. Our results suggest that cats use biological codes and paralinguistic information to signal mental state.
Two experiments were conducted to assess the influence of human attentional state, population, and human familiarity on domestic cat sociability. Sociability behaviors included duration of time in proximity and contact with the human and the frequency of meow vocalizations. Human attentional state influenced cat behavior, with cats spending significantly more time in proximity with the attentive human in both the pet (U(22) = 389, Z = -2.72, P = 0.007) and shelter groups (F(44) = 15.34, P = 0.0003). Cat population influenced sociability and shelter cats spent more time in proximity with the inattentive unfamiliar human as compared to pet cats (U(44) = 91, Z = 3.8, P = 0.0001) Additionally compared to pet cats, more individuals in the shelter cat group meowed at least once during the unfamiliar human inattentive phase (Fisher's exact test, P = 0.02). Human familiarity did not significantly influence pet cat sociability behaviors. Overall, a wide range of sociability scores was seen, indicating individual variation is an important consideration in cat social behavior. Future research in this area will predict conditions under which strong cat-human bonds form and establish a more comprehensive scientific understanding of cat behavior.
Practical relevance:
Cats are one of the most common companion animals in the world. However, relatively little scientific research has been conducted on cat behavior. With problem behaviors a leading reason for relinquishment of cats to shelters, or abandonment outdoors, solutions to address feline behavioral problems can have important welfare benefits. Because naturally occurring pheromones produce measurable species-specific responses in cats, the use of synthetic pheromone products consisting of the same compounds may activate a specific behavioral response in the receiving individual, allowing humans to better communicate with cats and manage feline problem behavior.
Aims:
In this article the scientific background for naturally occurring feline pheromones and semiochemicals and their impact on cat behavior is reviewed. This is used as a foundation to explore the three feline synthetic pheromones currently available and the empirical evidence that exists for their effectiveness. From this information, several recommendations for veterinarians and behavior professionals on the application of feline pheromone therapy in the home and veterinary clinic setting are presented.
Evidence base:
The efficacy of synthetic pheromones as a tool for the management of problem behaviors is a relatively new area of research and only fairly recently has the need to implement more rigorous research methodology been recognized.
Domestic cats (Felis silvestris catus) engage in a variety of relationships with humans and can be conditioned to engage in numerous behaviors using Pavlovian and operant methods Increasingly cat cognition research is providing evidence of their complex socio-cognitive and problem solving abilities. Nonetheless, it is still common belief that cats are not especially sociable or trainable. This disconnect may be due, in part, to a lack of knowledge of what stimuli cats prefer, and thus may be most motivated to work for. The current study investigated domestic cat preferences at the individual and population level using a free operant preference assessment. Adult cats from two populations (pet and shelter) were presented with three stimuli within each of the following four categories: human social interaction, food, toy, and scent. Proportion of time interacting with each stimulus was recorded. The single most-preferred stimulus from each of the four categories were simultaneously presented in a final session to determine each cat’s most-preferred stimulus overall. Although there was clear individual variability in cat preference, social interaction with humans was the most-preferred stimulus category for the majority of cats, followed by food. This was true for cats in both the pet and shelter population. Future research can examine the use of preferred stimuli as enrichment in applied settings and assess individual cats’ motivation to work for their most-preferred stimulus as a measure of reinforcer efficacy.
Leyhausen’s (1979) work on cat behaviour and facial expressions associated with offensive and defensive behaviour is widely embraced as the standard for interpretation of agonistic behaviour in this species. However, it is a largely anecdotal description that can be easily misunderstood. Recently a facial action coding system has been developed for cats (CatFACS), similar to that used for objectively coding human facial expressions. This study reports on the use of this system to describe the relationship between behaviour and facial expressions of cats in confinement contexts without and with human interaction, in order to generate hypotheses about the relationship between these expressions and underlying emotional state. Video recordings taken of 29 cats resident in a Canadian animal shelter were analysed using 1-0 sampling of 275 4-second video clips.
Although millions of cats live among humans worldwide the scientific community knows relatively little about cat behavior and cognition. Olfaction is an important perceptual sense for many members of Carnivora, however the role of chemical signals in cat social relationships is not fully understood. Research indicates chemical signals play an important role in many areas of cat behavior including mother-offspring and conspecific interactions and exploration of their environment. Chemical cues appear to play a role in stress and anxiety reduction, allowing cats to feel secure in their environment. A better understanding of cat chemical signals, especially as it relates to within and between species communication, may lead to an increase in cat wellbeing as humans can utilize this knowledge in applied settings. Therefore, the purpose of this review is to investigate how cats process and use chemical signals in social contexts and identify ways this information can be applied to address cat behavioral issues, such as inappropriate litter box and scratching behavior, and improve cat welfare, including species-appropriate ways of reinforcing the human-cat bond.
Reports of variability in the social behavior of the domestic dog (Canis lupus familiaris) are common across populations, breeds, and individuals. This has often been considered a challenge for characterizing the nature and origins of the domestic dog’s social cognition. Here, we propose that this variability might be explained by social plasticity, a trait that could contribute to the success of the domestic dog and facilitate the dog-human bond. Additional research specifically aimed at investigating population and individual variation in canine social behavior, such as attachment-style research, may provide important insight into domestic dogs’ biological success, as well as knowledge that could benefit both dogs and humans in a wide range of applied settings.
The domestic cat (Felis silvestris catus) has shared an intertwined existence with humans for thousands of years, living on our city streets and in our homes. Yet, little scientific research has focused on the cognition of the domestic cat, especially in comparison with human's other companion, the domestic dog (Canis lupus familiaris). This review surveys the current status of several areas of cat cognition research including perception, object permanence, memory, physical causality, quantity and time discrimination, cats' sensitivity to human cues, vocal recognition and communication, attachment bonds, personality, and cognitive health. Although interest in cat cognition is growing, we still have a long way to go until we have an inclusive body of research on the subject. Therefore, this review also identifies areas where future research must be conducted. In addition to the scientific value of future work in this area, future research on cat cognition could have an important influence on the management and welfare of pet and free-roaming cats, leading to improved human-cat interactions.
Given the social and territorial features described in feral cats, it is commonly assumed that life in multi-cat households is stressful for domestic cats and suggested that cats kept as single pets are likely to have better welfare. On the other hand, it has been hypothesized that under high densities cats can organize themselves socially thus preventing stress when spatial dispersion is unavailable. This study was aimed at comparing the general arousal underpinning emotional distress in single housed cats and in cats from multi-cat households (2 and 3-4 cats) on the basis of fecal glucocorticoid metabolites (GCM) measured via enzyme immunoassay (EIA). GCM did not significantly vary as a function of living style (single, double or group-housing); highly stressed individuals were equally likely in the three groups. Young cats in multi-cat households had lower GCM, and overall cats that tolerate (as opposed to dislike) petting by the owners tended to have higher GCM levels. Other environmental aspects within cat houses (e.g. relationship with humans, resources availability) may play a more important role in day to day feline arousal levels than the number of cats per se.
Canine shelters frequently have inadequate living conditions that affect the behavior of dogs. This study compared fear-appeasement and sociability reactions in shelter and pet dogs when they are confronted by an unfamiliar experimenter. Results indicated that shelter dogs used for this study showed more fear-appeasement behavior—tail down, ears down, and crouching—as compared with pet dogs. In addition, shelter dogs quite frequently remained closer to the individual, despite showing signs of fear-appeasement, as compared with pet dogs. Finally, shelter dogs remained near the door of the enclosure less often when compared with pet dogs. This difference might be accounted for by the lack of any attachment bonds among shelter dogs toward their caretakers. These results may be associated to the usual stressful conditions and limited interactions with human beings that may be observed in shelters with scarce resources.
Carnivores use various scent-marking methods. Semi-feral domestic cats (Felis silvestris catus) were observed to use the same means as their wild counterparts. Adult males performed most urine spray marking. Cats scratched tree bark, producing a visual mark, and probably used trees both as markers and for claw sharpening. Most scratching trees were located along frequently used paths rather than along territorial boundaries or scattered randomly throughout a home range. Bark consistency affected the tree species that were scratched, with soft bark preferred. Although deposition of faeces and urine was recorded, there was no clear evidence for their use as territorial markers; cats primarily eliminated away from the core area of the home range. Most faeces were buried, although exposed deposits were also observed. Cats also rubbed against objects, probably using glandular secretions from the face and tail areas to scent mark. Males rubbed objects more than females, and males scent marked more. Individual males may use different means of scent marking. Scent marking in this study supports the idea that cats do not defend territories, instead patrolling and reinforcing marks throughout a looser home range. The suggestion has been made that different forms of marking may serve separate signalling functions.
A descriptive study of the use of space and patterns of interaction of 14 unrelated, nonreproductive domestic cats (Felis catus) living together in a single-story house was undertaken, since these behaviors have rarely been described for cats in this common situation. Within the house, the cats kept to overlapping but individually distinct home ranges. The home ranges of males tended to be slightly larger than those of females, a pattern similar to that found in studies of feral cats outdoors. Three male kittens showed dramatic reductions in home range at approximately one year of age. Almost all individuals had favored spots where they could predictably be found within the rooms they frequented. While some individuals had unique spots that only they used, more commonly several individuals had the same favored spot within a room. Sharing of such spots was primarily the result of different individuals occupying the spots at different times, a kind of time-sharing rather than physical sharing. Time-sharing groups could be identified, some all female, some all male, some a mix. Certain individuals were identified as dominant or subordinant by their ability to control access to resources and/or by others conceding resources to them. However, overt aggression was rare, and there was no clear hierarchy. Tail positions could be identified and may have played an important role in helping this relatively large group occupy this relatively small home. Density calculations completed at the end of the study indicated that the group was living at approximately 50 times the highest densities observed in most studies of cats outdoors, yet stable groupings were maintained.
To investigate how socialization can affect the types and characteristics of vocalization produced by cats, feral cats (n=25) and house cats (n=13) were used as subjects, allowing a comparison between cats socialized to people and non-socialized cats. To record vocalization and assess the cats' responses to behavioural stimuli, five test situations were used: approach by a familiar caretaker, by a threatening stranger, by a large doll, by a stranger with a dog and by a stranger with a cat. Feral cats showed extremely aggressive and defensive behaviour in most test situations, and produced higher call rates than those of house cats in the test situations, which could be attributed to less socialization to other animals and to more sensitivity to fearful situations. Differences were observed in the acoustic parameters of feral cats in comparison to those of house cats. The feral cat produced significantly higher frequency in fundamental frequency, peak frequency, 1st quartile frequency, 3rd quartile frequency of growls and hisses in agonistic test situations. In contrast to the growls and hisses, in meow, all acoustic parameters like fundamental frequency, first formant, peak frequency, 1st quartile frequency, and 3rd quartile frequency of house cats were of significantly higher frequency than those of feral cats. Also, house cats produced calls of significantly shorter in duration than feral cats in agonistic test situations. These results support the conclusion that a lack of socialization may affect usage of types of vocalizations, and the vocal characteristics, so that the proper socialization of cat may be essential to be a suitable companion house cat.
The specificity of maternal-home cage odors governing home orientation was tested in 8- to 11-day-old kittens. Kittens were first tested for home orientation from the adjacent corner in their own home cages and cages of other mothers with litters of the same age. The majority of kittens oriented successfully in their own cages but not in strange mothers' cages. They then lived for 48 hr in the strange mothers' cages. At the end of this time they showed no improvement in orientation in their own home cages. Moreover, after an additional 24 hr in their own home cages they showed no improvement in their own home cages. Home orientation involves 2 odor components: 1 general to different mothers and 1 specific to each mother.
The presence of a thermal gradient in the home cage and its use in home orientation was studied in kittens from shortly after birth to 2 weeks. Responses on a thermal gradient outside the home cage were also studied. With the home region and a freshly washed cage floor either cooled or warmer, kittens were placed in the adjacent corner or the home. In one study kittens chose between a cooled home and a warmed diagonal region. On a thermal gradient kittens exhibited thermotaxic turning and thermokinetic response. Kittens initially used either thermal or olfactory cues to reach the home but began to use only olfactory cues towards the end of the 1st week. Similarly, warmth in the home region caused "settling" during the 1st week but thereafter warmth and olfactory cues were most effective. Kittens chose the cooled home region more often than the warmed diagonal corner responding to olfactory over thermal cues.
To determine whether cats develop clinical signs typical of separation anxiety syndrome (SAS) and the type and frequency of applicable clinical signs in affected cats.
Retrospective study.
136 cats with clinical signs typical of SAS in dogs. Subjects were evaluated during home visits.
Medical records of pet cats evaluated for behavior problems during a 10-year period were reviewed. Medical records of cats that displayed behaviors typical of dogs with SAS (eg, inappropriate elimination, excessive vocalization, destructiveness, or self-mutilation) were more extensively examined, and cats that displayed these behaviors only when separated from an apparent attachment figure were included in the study.
Behavior problems triggered by separation anxiety included inappropriate urination (96 cats), inappropriate defecation (48), excessive vocalization (16), destructiveness (12), and psychogenic grooming (8). Inappropriate defecation was identified in a significantly higher percentage of the neutered females in the study than in the neutered males. Seventy-five percent of the cats that urinated inappropriately urinated exclusively on the owner's bed. Psychogenic grooming was identified in 8 of the 40 neutered females but in none of the neutered males, whereas destructiveness was observed in 12 of the 92 neutered males but in none of the neutered females.
Results suggest that cats can develop SAS. Sex and breed differences in the frequency of particular signs of SAS in cats may exist. Feline SAS should be considered in the differential diagnosis of anxiety-related misbehavior in cats.
To evaluate associations between relatedness and familiarity with the affiliative behaviors of maintaining proximity and allogrooming in cats.
28 privately owned cats in 1 colony.
15 of the cats had 1 or more relatives present representing 5 genealogies. Each cat was observed in 15-minute intervals for 3.5 hours during the study. All occurrences of allogrooming behavior were recorded. At the onset of each 15-minute observation period and at 2-minute intervals thereafter, the identity and location of all cats within 1 m of the observed cat were recorded.
Relatedness and familiarity was significantly associated with the number of times a cat was within 1 m of another cat and how often a cat was groomed. For relatives and nonrelatives that were equally familiar to a given cat, relatives were significantly more likely to be within 1 m and to be groomed.
Familiarity and relatedness are significantly associated with allogrooming and proximity of another cat. This may be important when considering adoption of 1 or more kittens and when adding a new cat to a household in which other cats are present. Adopting small family groups may result in higher rates of affiliative behavior, stronger bonding, and lower incidence of conflict than periodically adopting single unrelated adult cats.
An increasing body of research work has made it clear that, while Felis catus can survive in the solitary state, social groups with an internal structure, are formed whenever there are sufficient food resources to support them. Most people who have cats have two or more cats. Failure to understand what will promote either friendly or aggressive behavior can lead to various behavior problems, including aggression and conflict over resources, such as food, resting sites and litterboxes. An understanding of the natural social organization, relationships and communication between cats is therefore essential, and is the subject of this paper.
