She also wants to encourage her kids to develop a passion for the ranching lifestyle.


Barn Cat "Ruler of the Clinic"

Barn Cat joined us as a kitten in 2001 after being left by someone to fend for himself in our clinic barn.
No matter how the staff tried to coerce him to be friendly and come into the clinic, he just wouldn't participate.

The staff had no alternative, but to simply feed and water him in the barn, which was where he deemed it appropriate to stay until the first cold winter day. The warm glow of the clinic must have been too much for him to handle because he decided to rush through the clinic door and has proceeded to rule the clinic ever since!


Teak "Official Greeter"

Teak has been with Valley Veterinary Clinic since 2003.
She spends most of her day curled up at the front desk, or basking in the sun in the reception area.

In her spare time she thinks up new ways to look cute for yet another low fat cookie.
