I wondered what the little girl did to the cat to provoke him into biting her.
THAT was my first question. How old was the little girl? I wouldn't have called either. I'd hate to see a cat put down simply because it was defending itself against a kid who provoked it. If the kid DOES have to go through the shots, maybe the pain will teach her a lesson on how to treat animals.

Catnapper is right, keep an eye on the cat to make sure it's okay. And please, keep us posted.
