Fishers, IN Animal Ordinances: Cat Rules (2026)

Several Chapter 91 provisions apply to cats in the City of Fishers. Section 91.04 requires every dog or cat three months or older to bear a permanent means of identification at all times - either a microchip with a registered number or a permanent tag on a durable collar showing the owner's name and phone number; an impounded cat lacking ID is microchipped before return at the owner's cost. Section 91.12 requires all cats three months and older to be vaccinated against rabies, with revaccination on the schedule the vaccine label specifies (within 12 or 36 months). Section 91.20 requires each cat over six months kept in the city to be sterilized by a licensed veterinarian unless an exception applies, including a free breeder's permit obtained from the Animal Control Officer, an approved-breeder status, or a veterinarian's letter that surgery poses a health risk. Section 91.05's at-large and restraint rules apply to cats as 'animals,' and § 91.06 treats free-roaming or nuisance behavior accordingly. For unowned cats, § 91.06(C) sets up a managed feral-cat colony framework: caretakers must register colonies with Low Cost Spay Neuter Clinic, Inc., use trap-neuter-return with ear-tipping, and vaccinate captured cats; feeding an unregistered feral colony is prohibited.
