Animals in zoos are never comfortable because they don't have large enclosures to roam climb hunt forage or choose a partner. Zoos buy and sell animals causing them to be separated from their families or mates which causes emotional and psychological damage to the animal. Breeding these animals can be profitable for the zoo but once the novelty of the newborn wears off it's future is bleak. The newborn is given the star treatment and then once the public stops going in to see it they feel a sense of neglect and do not adapt well to living in the zoo after that.
