Avoiding cat bites.

"When a cat throws itself on its side and shows its belly, most people misinterpret this behaviour and think that it wants its belly rubbed but will get grabbed by their hand and the cat will bite them."

What the cat is actually doing is showing a greeting behaviour and showing trust. It is actually an abuse of that trust to stroke its belly. What the cat would rather you do is to give it a slight head rub.

Useful! That can not only help you avoid cat bites, it can help you avoid concluding that cats are evil.
