The conditions animals are placed in negativity affects their health and can result with disease such as zoochosis. Zoochosis is not normally found in animals that live freely in the wild, but only captive animals. These diseases only showing up in captive animals prove that enclosing animals in cages only brings misfortune. These problems are serious and research has found that, “Keeping animals in captivity can, and does, cause immense mental suffering to the species put on display for our pleasure… Zoochosis is the term used to describe the stereotypical behaviour of animals in captivity.
