Exotic wild animals should never be domesticated or kept in houses for any reason. They are feral in nature and will defend themselves when they feel threatened. Some of the exotic animals like chimpanzees and apes are stronger than humans and when things go bad, they really go bad.
A woman was attacked by a domesticated chimpanzee in 2009 and lost all of her face in the attack, after it was bitten off by the chimp. She then received life saving surgeries and even a fully paid for face transplant surgery. See the difference between her face before and after the surgery.
