The use of camera traps for studying wild felids is a widely used method. Typically described as a non-invasive method of monitoring felids, there has been speculation that camera traps can affect wildlife behaviour. Camera traps are often used to study animal behaviour; thus, any effect camera traps may have on felid behaviour is important to docu...
