My iguana bit my wrist for no reason, is it time to grill it?

You realise that most of the time when an animal bites you, it's because you have done something wrong. Like my hamster bit my mate once when she was being far too rough with it, and she said "he's too vicious, you need to put him down." But it was the way she was holding him. Maybe you scared it? Or were wearing perfume or something? Don't blame the animal when it could have been your own fault.
