Summary

Marin County requires every cat to be vaccinated against rabies, whether owned by a household or a colony caretaker, under Section 8.04.040(b) of the county code. Unlike dogs, cats need no annual county license, but veterinarians must report vaccinations to the animal services agency within thirty days, and unvaccinated cats can be denied return from the shelter.

These county ordinances apply to unincorporated areas of Marin County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Frequently Asked Questions

Do I need to license my cat in Marin County?
No. Section 8.04.030's dog license requirement applies only to dogs over four months old, and the license fee schedule in Section 8.04.060 is likewise limited to dogs. Cats have no county licensing scheme, but Section 8.04.040(b) still requires every cat to be vaccinated against rabies.
What happens if my cat has no rabies vaccination and ends up at the shelter?
Section 8.04.130(c) requires that impounded cats four months or older be released to their owner "with proof of a current rabies vaccination." Without that proof, the Marin Humane Society will not return the cat until the vaccination is obtained and documented.
Does a feral cat colony caretaker have to vaccinate the colony?
The code's language reaches beyond formal ownership: Section 8.04.040(b) applies to "any person in possession, control or ownership/guardianship of any cat," which covers a person who feeds and manages a colony. The county code does not, however, set out a separate feral-colony permit or registration process.
Do veterinarians have to report cat vaccinations to the county?
Yes. Section 8.04.040(c) requires any veterinarian, at a fixed office or a mobile clinic, to send the animal services agency a copy of the rabies vaccination certificate for any cat or dog they vaccinate, due within thirty days of the vaccination.
