Summary
Unlike dogs, cats in Irvine are never required to wear a City license tag: Sec. 4-5-211 makes cat registration optional, though any cat that is registered must carry a current one-year rabies certificate. Loose cats aren't covered by the leash law, but owners are still on the hook for trespass, damage, and excreta nuisances under the general animal code.
Sec. 4-5-211. - Registration of cats. Cats over four months of age may be registered with the City in the same manner in which dogs are registered. Cats must have a current rabies vaccination valid for the entire one-year registration period.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 20 | Zoning: Supplement 16).
Full Breakdown
Sec. 4-5-211 provides that "cats over four months of age may be registered with the City in the same manner in which dogs are registered," and requires a "current rabies vaccination valid for the entire one-year registration period" for any cat that is registered. That stands in contrast to Sec. 4-5-201, which makes dog registration mandatory. Irvine's code contains no dedicated feral-cat-colony or trap-neuter-return ordinance; free-roaming cats are instead governed by the general "any animal" provisions in Chapter 7 of Title 4, Division 5. Sec.
4-5-702 bars any animal, cats included, from trespassing onto someone else's property without consent, and Sec. 4-5-710 makes an owner responsible for cleaning up any animal's excreta left on a public sidewalk, park, or another person's improved private property. Cats are also outside the leash requirement in Sec. " On numbers, Sec. 4-5-106 caps a private animal owner at three adult cats for personal use before the property becomes a "private kennel" requiring a permit under Sec. 4-5-601. All of these provisions are enforced by the Director of Public Safety's animal services officers under the citywide enforcement chapter, Sec. 4-5-1301.
Violations & Fines
There is no penalty for simply not registering a cat, since registration is optional. Violations instead arise when a cat trespasses or damages another person's property (Sec. 4-5-702, 4-5-703), when its excreta is left uncleaned on public or another's private property (Sec. 4-5-710), or when a household exceeds three adult cats without a kennel permit (Sec. 4-5-106, 4-5-601). Any of these is enforceable as a misdemeanor under Sec. 4-5-1301, with each day of a continuing violation charged as a separate offense.
