That's silly. Animals kill zookeepers all the time.......how about the woman who was mauled by the monkeys her friend kept. Can't remember where but Oprah did a show on her she has no hands or eyes now. Denver zoo had a jaguar that killed the zookeeper that fed it everyday. Animals are animals. You may think at times you have bred or trained out their natural instincts and that you are the best animal trainer whisperer ever.............and then they show you otherwise.
