Hmm ever heard white tigers are inbred, not purebred?
An animal can be inbred and still purebred. Many purebred dogs are inbred. Pugs, for one example. America's white tigers are crossbred with several tiger subspecies along with being inbred.
To be honest when I clicked on this thread the title did make me think this was going to be a discussion on what animals you hate to see kept as pets...
As for animal pet peeves, the previously mentioned ones about the annoying things that visitors do in zoos (hey, someone should make a thread about that!) all ring true for me. Also the normal calling apes, monkeys and so forth.
