Members of the cat family are highly motivated to hunt, but in captivity are unable to do so for a variety of reasons. This inability to hunt may reduce their welfare. In this study we used a moving bait to stimulate and release hunting motivation in... Read More about The effect of a moving bait on the behaviour of captive cheetahs (Acinonyx jubatus).
