Twin Falls, ID Animal Ordinances: Cat Rules (2026)

Twin Falls regulates cats lightly. The at-large provision, Section 6-3-13 in Title 6, Chapter 3 (Animals), makes an owner liable after a written warning from Code Enforcement when any animal, excluding domestic cats, runs at large or is not kept securely confined on the owner's premises. The infraction carries a fine of three hundred dollars ($300.00). Cats are carved out by name, so a roaming house cat is not covered by that section. The separate dog at-large definition in Section 6-4-1 is limited to dogs.

Chapter 4 is titled Dogs and Cats, but its license and registration provisions are written for dogs. Section 6-4-2 requires dogs six (6) months of age or older to be licensed and registered, and Section 6-4-7 requires antirabies vaccination for every dog. The sections read here print no cat license requirement and no cat tag.

The operative cat limit is the kennel rule, Section 6-4-9(B)(2). It provides that no person shall harbor or possess more than four (4) dogs and four (4) cats within residential zones within the city of Twin Falls, and that kennels are permitted only in commercial or industrial zones. Section 6-4-1 defines KENNEL as a lot, building, structure, enclosure or premises where more than four (4) dogs and four (4) cats over the age of four (4) months are raised, kept, housed, or boarded for a fee, or for a period of more than thirty (30) days, excluding licensed veterinary offices. A kennel license costs an annual fee of one hundred dollars ($100.00), renewable each March 1, and requires approval through the code enforcement officer and an inspection by a Twin Falls animal control officer. Kennel records must show each cat's description and, for any cat over four (4) months of age, a current valid rabies certificate.

General duties still apply to cats. Section 6-3-7(B) requires all other animals found in city limits, including pets, to be kept in sanitary conditions with sufficient access to shelter, food, and water. The code printed in the sections read here contains no feral colony provision.
