tail biting/chewing

Question
I have 2 one-year old sisters. The quiet shy one was found today having chewed 1/3 of the skin off of the the end of her tail. What's going on?

Answer
I'm not sure what type of rodent you are talking about. It sounds like fleas or some other pests to me. You have to take them to the vet and get some safe medication to get rid of them. Don't buy anything over the counter because it is not safe. See a vet.
