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.
Stereotypy (non-human); repeated, relatively invariant behaviours with no apparent purpose (multiple types). [34] Stress/anxiety; behaviours associated with being exposed to a stressor (e.g. loss of appetite, social withdrawal). [35] Stone chewing; chewing stones or rocks without swallowing them. [36]
A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] pl.: zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human. When humans infect non-humans, it is called reverse ...
The virus, also known as Peste des Petits Ruminants (PPR), does not affect humans but is highly contagious among goats and sheep and can kill up to 70% of those infected. About 8,000 animals have ...
Humans may first encounter coccidia when they acquire a dog, cat or bird that is infected. Other than T. gondii, the infectious organisms are canine and feline-specific and are not contagious to humans, unlike the zoonotic diseases. [citation needed]

The smallest animal that can kill a human is the Naegleria fowleri amoeba. N. fowleri does this by crawling up the target's nose and eating the targets' brain. Most attacks happen in moist areas like ponds or lakes. [27] [28] In the middle is the blowfish (fugu) that can kill animals with its toxic organs that contain tetrodotoxin. [29]
Mountain goats introduced in the 1920s into Washington’s Olympic Mountains were in time found to be a nuisance there, in particular while seeking human urine and sweat for its salt content, the park lacking natural salt licks, and even aggressively approaching human visitors. [14] One such goat killed a hiker in 2010. [15]
