Our hospital cats Ben and Jerry, can often be found roaming around, demanding attention. They are super sweet and each one has their own personality. Ben is a strong willed and curious little guy, whose favorite thing to do is pester his brother Jerry. Jerry is much more shy than his brother. He loves to play with his cat toys and when Ben isn't pestering him they have a good time rough housing with each other.

Ginger is another rescue that Rancho West took in. From the moment we adopted her, she took over Dr. Stiles' office and made herself at home. She is very feisty and often demands Dr. Stiles' attention while she is writing up charts or going over cases.

Bella is a rescue cat that Rancho West adopted. She can almost always be found napping in her extremely fancy bed. She will also always be more than happy to take any spare treats you might have.
