So says Amy Sutherland. And you've got to believe her. She wrote the book. Well, a book. It's called Kicked, Bitten and Scratched: Life and Lessons at the Premier School for Exotic Animal Trainers.
Seriously though, the stuff she says makes sense. Reward behavior you would like to see more of. (Though the flip-side, ignoring the stuff you don't like, isn't easy for most of us.) Understand your exotic animal bit o' fluff. If they're doing things you don't like, find other stuff they like to do that would make it impossible to get up your nose and encourage that instead. Examine your own behaviour and see whether you're contributing to the problem. Elementary stuff, I would have thought. But with our track record, we should shut up now.
