Who's really in charge....



“Don’t worry, I didn’t get loose. I live here.” Clementine came to live with us in 2019. She was brought in by a good Samaritan as a stray youngster. With no microchip, and no one to claim her, she became our meet and greet kitty. She mostly lives in our treatment room, but don’t be surprised if you catch her sitting in the lobby looking out the window.
