About Us

Our Philosophy

We treat every cat as if it was our own. 

In the words of Dr. Donna Shannon, Veterinarian and Owner:
Why a cat hospital?
While I enjoy the company of many species of animals, the feline is the one that brings a ray of sunshine to me, no matter what else is happening.  Having practiced in both the large animal and small animal field, I saw the neglect of, often from lack of interest and sometimes downright distaste for, the feline patient.  Because cats don't like to leave their environment, it is up to us to provide them with an environment that is as stress-free as possible, and most of all to treat them with understanding and respect.

Because every pet is different, we strive to tailor our care to every pet's individual needs.

Because every pet is different, we strive to tailor our care to every pet's individual needs.
