About us


To ensure a pleasant visit for your furry family members, our office offers separate entrances to minimize anxiety for both cats and dogs alike.  We were awarded gold level Cat Friendly Practice certification by the American Association of Feline Practitioners in 2012. To achieve and maintain this title, we have met the required standards for facility layout, and have ensured that our staff understands the specific needs of cats. In addition to keeping our feline friends happy, we also offer many other options to accommodate your other four-legged family members – all  dogs, cats, rabbits, ferrets, guinea pigs and pocket pets are welcome!
