Summary

Wilmington doesn't license or leash cats, but a cat counts as a public nuisance animal if found at large more than four times in 12 months, unless it belongs to a registered trap-neuter-return colony, which the code says has no owner and can't be "at large."

Public nuisance animal means any domestic animal or group of domestic animals which: (1) Is found at large more than four times in a consecutive 12-month period of time. Cats participating in a trap-neuter-return population control program do not have owners and shall not be considered "at large";

Full Breakdown

City Code § 3-1 defines a "public nuisance animal" to include one found at large more than four times in a consecutive 12-month period, but carves out cats in a trap-neuter-return (TNR) population-control program, deeming them ownerless and exempt from "at large" status. Unlike dogs (§ 3-9, § 3-10(a)), cats face no city licensing or leash mandate. Female cats in heat must still be confined under § 3-10(b) so they can't contact other animals except for planned breeding.

Violations & Fines

A cat cited as a public nuisance animal may be impounded by police or animal welfare officers; under § 3-7.1 the owner must surrender it on demand and it's unlawful to refuse. Redemption requires paying shelter/boarding fees, and unclaimed animals become city property after five days.

Yes. § 3-1 says TNR-program cats have no owner and can't legally be considered "at large."
