@livinlikelarry494: zoochosis: "If the captive environment does not fully cater for the species-specific needs of an animal, or if it imposes unnatural stress or frustration, there can be a deterioration in the animal’s physical and mental health. This may manifest in the development of physical disease or abnormal behaviour. Abnormal behaviour in captive animals can include stereotypic behaviours – highly repetitive, invariant, functionless behaviour, such as repetitive pacing, swaying, head-bobbing, bar-biting, over-grooming or excessive licking. These behaviours result from 'the frustration of natural behaviour patterns, impaired brain function, or repeated attempts to deal with some problem'"
