I've had to nail a dog that attacked me once (it was a total psycho).
My cat I used to razz up with his fish on a string and I could then put my hand down in front of him and he'd grab it and bite it, but only gently ( like a dog playing). He'd sleep under my armpit with his chin on my shoulder just purring the whole night. It depends on the animal, its treatment, environment, and familiarity and feelings towards people it doesn't know well.
