Licensed Veterinary Technicians

LVT’s are similar to registered nurses in the human profession. They care for your cat, administer anesthesia, perform dental procedures, monitor the health and well being while your cat stays with us. LVTs are your cat’s voice while in the hospital. They are trained to observe pain and make sure their stay is as stress free as possible.

Office Cats


RIP Lucy 07/01 - 05/17

Lucy enjoys long naps in her basket, eating, and basking in the sun. She has been our office cat for over five years. She spends most of her time near the front desk where her favorite person, Ronda, works.


RIP Mylo 07/97 - 07/18

Mylo is 21 years old and full of spunk. She is our bathroom office kitty, but sometimes finds her way to the doorway to bask in the sun and to say "hi" to our patients and their families with her very distinctive (loud) meow.
