Summary
New York City requires every cat owner to have their cat sterilized if the cat is ever allowed to roam outside the home, with the Health Department authorized to demand proof on request.
Every owner of a cat who permits such cat to roam outside the interior of the owner's dwelling shall have such cat sterilized. At the request of employees or authorized agents of the department, owners shall provide proof satisfactory to the department that a cat found roaming has been sterilized. The Department shall not seize a cat solely on the ground that the cat has not been sterilized.
Full Breakdown
Administrative Code § 17-804(d) makes sterilization mandatory for any cat "permitted to roam outside the interior of the owner's dwelling", not just strays. Owners must show proof of sterilization if a Health Department agent asks after finding the cat roaming, but the code bars seizure of the cat solely for being unsterilized. The same section separately requires city shelters and pet shops to sterilize dogs and cats before adoption or sale, with narrow exemptions for medical risk, registered show or champion animals, and service dogs.
Violations & Fines
No fine is written into § 17-804(d) itself; the Health Department can only demand proof of sterilization from an owner whose cat is found roaming and may not seize the cat for noncompliance alone.
