Poor boof!!! I would get him to a vet to get him checked out ASAP. My old rabbit Jaxom got attacked by my other rabbit Julian and he was in a lot of pain. The vet stitched him up, put him on antibiotics and pain meds. Poor Boof must be in a lot of pain. Also, it is necessary for a rabbit to be able to eat, it can cause serious harm to Boof's digestive tract if he stops eating. I would highly suggest getting him to vet as soon as you can!
