Also ask about pain relief. A lot of vets give an injection to help with the pain after the operation, but this only lasts about 24h. If you know any women who've had a hysterectomy you'll know the pain lasts much longer than that. Ideally the vet should routinely give a liquid pain medication for you to take home, sometimes you have to ask, if they say no then I wouldn't use that vet. Just because rabbits hide pain well doesn't mean they aren't in pain.
