Full Breakdown

Ann Arbor doesn't license cats the way it licenses dogs, but § 9:47(12) makes it a violation for 'the owner of a cat older than 6 months' to fail to have it 'at all times immunized against rabies.' Cats also fall under the chapter's general nuisance and impoundment rules, an owner can be cited if a cat causes a noise or sanitation nuisance, and an animal control officer may impound an animal showing rabies symptoms or that bit someone under § 9:48(8). The rabies requirement carries the chapter's standard fine.

Violations & Fines

Civil infraction, fine up to $500 under § 9:47(12) for an unvaccinated cat over 6 months; noise and sanitation nuisances carry the same penalty.
