why do cats bite peoples feet?

They're doing it because:

1. They want to play

2. They could be bored or hungry

Also ignore Sandy, she's a sick freak. Animal abuse is NEVER the answer!

Cats are ambush predators.  My cat has torn the ankles out of every pair of tights I have.

Jackson Galaxy said the reason why they attack your feet is because they see your feet as mice or prey. It is also probably a phase since many kittens go through this phase.

Not all cats do that. Some do it because they are playing or showing aggression.

Cats are jerks....

smack it with a newspaper. the mother should have shut this biting thing down, but didn't. so you have to.
