I have owned pet rats for many years and have been to this clinic a few times. Dr. M is ok with rats but I DO NOT recommend Dr. Booker (who i've seen about 3-4 times).
She says she knows a lot about rats, but the things she says contradicts many experts as well as my own years experience. She's rough handed, doesn't listen and jumps on any opportunity to make a buck. If you bring your rat in, make sure it's with Dr. M
