COVID-19 Response
Although we’re all breathing a sigh of relief as the vaccine is more available and seems
protective, the virus is still present, variant strains present more uncertainty, and not all people
are vaccinated or will be.
In order to lessen the impact of COVID, and for us to be able to continue to provide this
essential service for your cats, we’ve decided to continue our safety precautions, and ask for
your help.
At the time of your appointment, please remain in your car while we admit your cat.
The doctor will call you after her evaluation, and devote the time you need to understand her
findings and plan.
Offering the safest, most reliable treatment for Feline Hyperthyroidism
Hyperthyroidism is the most common hormonal disease of cats resulting from excess thyroid hormone, which puts significant and potentially fatal stresses on the body. Radioiodine therapy is the safest and most effective therapy available. It's less risky than surgery and doesn't require medicating your cat daily for years. Most cats stay a couple nights before returning home — happy and healthy.
