Tommy is our resident clinic cat that came to us a few years ago with a broken leg when he was just a kitten.

He is extremely photogenic and always keeps us on our toes. In his spare time, he loves to nap, eat, play in any box you put on the floor, and comfort hospitalized patients in their time of need. We celebrate Tommy every Tuesday on our Facebook and Instagram. Tune in to see what kind of mischief he gets into every week!
