Animal psychopathology
Animal psychopathology is the study of mental or behavioral disorders in non-human animals.
Historically, there has been an anthropocentric tendency to emphasize the study of animal psychopathologies as models for human mental illnesses.〔Owen, J. B., Treasure, J.L. & Collier, D.A. 2001. Animal Models- Disorders of Eating Behaviour and Body Composition. Kluwer Academic Publishers, Norwell; Massachusetts.〕 But animal psychopathologies can, from an evolutionary point of view, be more properly regarded as non-adaptive behaviors due to some sort of a cognitive disability, emotional impairment or distress. This article provides a non-exhaustive list of animal psychopathologies.
==Eating disorders==
Animals in the wild appear to be relatively free from eating disorders although their body composition fluctuates depending on seasonal and reproductive cycles. However, domesticated animals including farm, laboratory and pet animals are prone to disorders. Evolutionary fitness drives feeding behavior in wild animals. The expectation is that farm animals also display this behavior, but questions arise if the same principles apply to laboratory and pet animals.
