Wild rabbits survive by hiding out in their burrows.

Claws and teeth! I have several rabbits and my oldest female fave me a very good bite on my wrist. I still have a scar. I also used to have a lot of scratches. Until I learned to properly hold my rabbits. They have very strong back feet with pretty big claws. If you ever meet up with one who does not want to be messed with you will find out what they use. Believe me they can do pretty well against people!

They protect themselves my claws and teeth.
