A lot of cats are not that social.

You know, having raised animals all my life for 50-something years, I would say that you know, I'm fascinated by cats.

I could do a franchise for the end of everything. 'The End of Dogs,' 'The End of Cats.'

I must say that in the last 20 years, I don't know of one zoo visitor that has been killed or maimed that bad by an animal in the zoo. Obviously, as zookeepers, our job tends to be dangerous at times.

Alligators and crocodiles are some of the most aggressive creatures on the planet - they'll take down a boat if you come up to their nest.

I've been out all over the world tranquilizing animals.
