Kelly, I don't know how to help, but friend of mine had a girl bunny who did the same, not with another rabbit, but with a tennis ball That was hilarious!
Ok, sorry, didn't help you at all. Have you asked from the vet? You said she's not fixed, do you think that makes a difference? I don't know all that much about rabbits, but I know that Faith is cutie!!!! And Thomas too!!! And nice to hear from you Kelly!
