Well, I'm within 20 minutes of the U of Penn Vet Center, one of the top in the country. I won't go there, you'll literally pay 4x what you'd pay with any good vet.
The vet I have is very good. Cat specialists have to be by the simple fact that when they specialize they've narrowed the hell out of their business. I don't like taking cats to a vet that does all sorts of animals, I've had some bad experiences, and heard worse stories (the vet that couldn't vaccinate a cat because it was throwing a fit so they anethetized it and the cat died from anesthesia comes to mind -- true story, happened to my husband's friend).
For most cats the experience of being shoved into a carrier and going on a car ride is terrifying enough combined with smelling all the lingering odors of strange cats, but combine that with animals that they consider predators?
Also, I don't like the way vets that also treat dogs usually handle cats. Most of them don't understand cat psychology. A cat freaks out and the vet treats it like a dog that's misbehaving, shake a cat and speak firmly and you've just escalated things and frighten the animal further. My vet handles cats like they're sweaty sticks of dynamite, very gently, speaking softly, no matter how bad the scene gets. They were working with a feral cat when I dropped the girls off for surgery, talk about caterwauling.
