How much does it cost to get a rabbits teeth filed down?

It all depends on what you vet charges. BUT get used to the idea that it will have to be done EVERY month for the rest of the rabbit's life. It gets VERY expensive. The rabbit should be put down because if you don't clip it's teeth it can't eat and will die anyway. Do not use this rabbit in any breeding program even if you decide to go to the expense of clipping your rabbit's teeth. It is a genetic condition.
