Unmatched Care & Experience

Colorado Cat Veterinarian PatientsYou’ve found the perfect site to find a Colorado feline veterinarian. We’re centrally located in Castle Rock, Colorado to provide feline veterinary services, as well as cat boarding and grooming, to clients from Centennial, Highlands Ranch, Parker, Colorado Springs, Denver, and many surrounding communities in addition to Castle Rock. There is no other Colorado cat veterinarian Board Certified by the American Board of Veterinary Practitioners.  So, when we say “specialist,” we mean specialist.

Cats Only Facility

Dr. Olson is the only Board Certified Colorado cat veterinarian operating a feline-exclusive hospital dedicated exclusively to his patients. From your cat’s perspective, this means no barking dogs, no sounds or smells of other species. From your perspective, this means a clean, quiet environment with the very latest in diagnostic and medical equipment dedicated entirely to the cat. Specialized equipment is expensive, and very few hospitals are willing to commit the resources that we have on just the cat. Watch our video to see a quick tour of our Castle Rock, Colorado feline veterinary hospital.


At Cat Specialist, we see many patients who are referred for a second opinion by general practitioners. But did you know that you can self-refer to the best feline vet in Colorado? We see patients whose owners self-refer because they have not gotten the expected results elsewhere. The most common compliment we get is “If only I had come here first!” This is because we know what’s going on with the cat, and are far more likely to be able to resolve the problem correctly and quickly, than the general practitioner.

Feline Hyperthyroidism & Radio-Iodine (I-131)

Cat Specialist treats feline hyperthyroidism with radio-iodine (I-131), the only cure for feline hyperthyroidism. We are the only radio-iodine (I-131) treatment center in Colorado where your cat is monitored daily by a Board Certified Feline Practitioner. If you have a hyperthyroid cat, you should click here for more information.

More than just the best cat veterinarian in Castle Rock, we’re the best feline vet in Colorado! We’re easy to get to, and you can find directions on our Contact Us page. If you want to ask a question, just call 303-663-2287 or e-mail us, we’re glad to help.
