If I were ever to get a rat again, I would A. get two and B. see Dr. Korber. Her treatment of our cockatiel was very thorough and knowledgeable. The clinic is a little on the expensive side, however, it is well worth it. My rats have been treated by both. They've performed tumor removals with great results, they have also spayed my rats and I have no complaints with their service.
Prices are great and the service is even better.
Pawel Biernacki and Dr. These people are great. They have neutered my male rat and also amputated part of the males tail due to a mystery accident. They bend over backward and I highly recommend them. They do not handle cats and dogs.
