I agree. In all my years breeding rats I have only had something like this happen once. One of my females got her tail caught in the cage wall. She gnawed it free. It got infected and after weeks of antibiotics it started to heal up. Even though she was healthy when I did try and reintroduce her back to a male he wanted nothing to do with her (my guess was he could tell she was defective) and ended up beating her up really badly. After this I had to amputate the rest of the tail and she lived a short life as a pet (got sepsis is my guess and died)

Long story to say take her to the vet and I don't suggest you try and breed her just keep her as a pet.

Hope this helps,
