While most zoos claim that they provide a habitat for their animals that is as close to their natural habitat as possible, this is not so. Because the animals are not provided with their true living conditions, it is not only impossible to observe them engaging in natural behavior, but we often witness abnormal, psychotic behavior, known as zoochosis. This sickness is marked by symptoms such as pacing, neck twisting, head bobbing, biting of cage bars, and other repetitive behaviors. I'm sure we've all witnessed this unfortunate situation at one point or another. The wings of birds may be clipped so that they can no longer fly.
Little water is granted to animals that are aquatic by nature.
Animals are found either individually or in pairs, whereas in the wild, they would be traveling in large herds or with families. Organized feeding and breeding schedules replace natural hunting and reproductive behaviors. Zoochosis is not restricted to a few, less than ideal zoos. As a matter of fact, a global study found zoochosis to be rampant in incarcerated animals all over the planet. If anything, they've been educated in the effects of cruelty on suppressed animals.
