Jefferson County does not license cats or impose a leash law on them, and cats found at large are generally not impounded. Cats count toward the 3-pet zoning limit, and owners must provide proper care, report bites, and honor rabies quarantine.
The Animal Control Regulation's licensing and leash provisions apply to dogs, not cats. On impoundment, the ordinance specifically excludes cats from the at-large impound rule that covers other pets. Animal Control may still impound a cat that has bitten a person or been exposed to rabies-vector wildlife, or one that is sick, injured, or abandoned. Cats are counted among the 3 household pets allowed per residential lot under zoning. Owners must provide proper care, may not allow excessive feces/urine accumulation, and must report cat bites causing bodily injury within 24 hours.
No cat licensing or leash penalty. But failure to provide proper care ($100 min), excessive feces accumulation ($50 min), or failing to report a bite / violating quarantine ($50–$100 min) are petty offenses.
