Cupertino, CA Animal Ordinances: Cat Rules (2026)

020 limits any premises to three cats over four months of age (and two dogs), and further caps unspayed animals at one unspayed cat and one unspayed dog over four months old per property; a female is rebuttably presumed unspayed unless the owner shows proof, though a veterinarian's written statement that the animal can't be spayed for health reasons, or is biologically incapable of breeding, satisfies the requirement instead. Licensed veterinary premises and City-permitted private kennels, commercial kennels, pet shops, animal menageries, or shelters are exempt from the cap.

030 requires every cat over four months old to carry a current anti-rabies vaccination approved by the State Department of Public Health, revaccinated on the schedule the state sets, and compliance is a condition of getting or renewing the City license. 050 makes it unlawful to maintain or board an unlicensed cat four months or older, with narrow exceptions for a nonresident's cat kept in the City fewer than thirty days in a twelve-month period, or a cat brought in for a show or exhibition scheduled within ten days. 080). 090.
