We have four cats and have been using Dobson Animal Ranch for almost a year. It's clean and convienent and the prices are normal.
They have forms for authorizing someone like a petsitter to make care decisions in your stead (which is very important for us as we travel often.) They were also kind enough to fax our vaccination information to a kennel on a holiday weekend when our AC went out and we needed to kennel the kitties.
They are well informed and did not push services. When one of our cats had a reaction to a vaccine, they were great about keeping us informed and the follow up care has been outstanding.
