Some abnormal behaviours may be related to environmental conditions (e.g. captive housing) whereas others may be due to medical conditions. The list does not include behaviours in animals that are genetically modified to express abnormal behaviour (e.g. reeler mice). A polar bear performing stereotyped pacing.
Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1] As such, the diseases of these animals are of great economic importance to humans.
The syndrome was an economically significant issue for sheep breeders in the 1980s, [8] but with strict testing and breeding programs it has become less common. [ 8 ] The mutation which causes spider lamb syndrome is found on ovine chromosome 6, [ 9 ] and involves the inactivation of fibroblast growth factor receptor 3 . [ 10 ]
Scrapie and other transmissible spongiform encephalopathies are caused by prions. [19] Prions were determined to be the infectious agent because transmission is difficult to prevent with heat, radiation and disinfectants, the agent does not evoke any detectable immune response, and it has a long incubation period of between 18 months and 5 years.

Vacuum activities (or vacuum behaviours) are innate fixed action patterns (FAPs) of animal behaviour that are performed in the absence of a sign stimulus (releaser [broken anchor]) that normally elicit them. [1] This type of abnormal behaviour shows that a key stimulus is not always needed to produce an activity. [2]
