There is no regulation for vaccinating your cats however, the Animal Safety Division highly recommends rabies vaccinations for all cats residing in the county. Rabies has been found in bats in Pitkin County and if a cat has contact with or consumes a rabid bat a life threatening illness is likely.
We also recommend a Feline Leukemia vaccination. Feline Leukemia may cause various blood disorders, and may lead to a state of immune deficiency that hinders a cat's ability to protect itself against other infections. Most importantly, it is also very contagious to other cats.
