Summary
Renton requires every cat over four months old to carry a City animal license under RMC 5-4-1, applied for within 30 days of acquisition, with an unlicensed cat a civil infraction. Unlike dogs, cats are expressly exempt from the City's at-large ordinance, RMC 6-6-1, so a roaming cat alone isn't a code violation unless it injures someone or damages property.
5-4-1 REQUIRED AGE FOR LICENSING AND PENALTY FOR VIOLATION: A. It shall be unlawful to own or keep a dog or cat of more than four (4) months of age within the City unless the owner or custodian thereof shall have a valid animal license for each such animal. B. A violation of this section shall constitute a civil infraction punishable as set forth in Section 1-3-1 of this code. ... 6-6-1 CONTROL OF ANIMALS OFF OWNER PREMISES: A. Animal at Large: An Owner is in violation of this Section if his or her Animal is At Large. This subsection does not apply to (a) cats, or (b) dogs in an Off Leash Dog Park so long as the dog and Owner are in compliance with all other applicable rules and regulations.

Full Breakdown
RMC 5-4-1.A makes it unlawful to own or keep a dog or cat over four months old in Renton without a valid City animal license for that animal, and 5-4-2.A requires owners to apply and pay for the license within thirty days of acquiring the cat, renewing it before expiration. Economically Qualified Residents, defined as low-income senior or disabled residents receiving or eligible for discounted water rates, can get a special lifetime license instead, capped at three lifetime licenses per household for any combination of cats and dogs.
Failing to license a cat is a civil infraction under 5-4-1.B, punishable under RMC 1-3-1. Where Renton diverges sharply from most cities is at-large enforcement: RMC 6-6-1.A makes it a violation for an owner to let an 'Animal' run At Large, but the very same subsection carves out an express exception, 'This subsection does not apply to (a) cats.' That means a cat wandering off its owner's property is not, by itself, a code violation the way an at-large dog would be. Cats aren't entirely unregulated, though: 6-6-1.B still makes an owner liable if their animal, cat included, injures a person or another animal or causes property damage while off the property, and an Animal Control Officer can still impound any at-large animal under 6-6-2.A if it poses a public safety, health, or welfare threat. An impounded unlicensed cat must be licensed before redemption under 6-6-2.B1.
Violations & Fines
Owning an unlicensed cat over four months old is a civil infraction under RMC 5-4-1.B, punished per RMC 1-3-1, including fines and possible late-fee surcharges under 5-4-2.D. A cat that injures a person or animal, or damages property, while off its owner's premises is a misdemeanor under RMC 6-6-1.B even though ordinary roaming isn't itself an at-large violation for cats.
