Well I would have to say Bowman Animal Hospital http://www.bowmananimalhospital.com/ . I bring my cats here for their annual shots, rabies shot, checkup, etc. I like that fact that the staff is very polite, gives you estimates on price (in writing) before they do anything, and are on time. My pets have have seen Dr. Smith and Dr. Goodwin. I also like how they spend their time going over what they found with me and I am in the room during the checkup. They let me know what is important to have done, what is not but may be just a good idea. For example, they said if I was going to get my pets chipped to do it when they were spade-neutered while they are under. But I was also told it was up to me, and it was just something extra. The only downside is that I live in Cary so I have to drive a bit to get there. It may be a little pricey. I typically spend around $250 every year for bloodwork, de-wormer, checkup, rabies shot, etc for both cats (total). They do offer a multiple discount, so bring them all in at once and get your money's worth.
I did not have my cats spade/neutered here because it was too expensive. I got a coupon from the SPCA and you take that to specific locations to get your pet taken care of. Too many pets are being euthanized, have your pets spade-neutered. There are places in can be done for free or very cheap. http://animalkind.org./home.html
I had my pets spade-neutered at Animal Kingdom using the voucher from SPCA and paid extra to have it done using a laser instead of a blade. http://www.animalkingdomvet.net/index.php
They were also very nice but not as informative as Bowman.
