Full Breakdown
Hamilton's spay/neuter mandate is scoped to community, or feral, cat colonies rather than owned pets generally. " That sits alongside parallel duties to "make all reasonable efforts to vaccinate the community cat colony population for rabies" (D(1)(b)) and to "ear-tip community cats in their community for easy identification purposes" (D(1)(d)). C(2) if the caregiver meets these sterilization, vaccination, feeding and ear-tipping standards; a colony that falls short remains subject to Chapter 108's ordinary licensing and at-large rules. Chapter 108's general definitions separately define NEUTER as "the act of surgically sterilizing a male animal by a licensed veterinarian," underscoring that only a licensed vet's work counts toward the program. B, so caregivers bear the sterilization expense themselves or through outside rescue partners.
Violations & Fines
A colony that does not reach the 90% sterilization threshold or the vaccination and ear-tipping duties in § 108-25.D loses the licensing/at-large exemption in § 108-25.C(2), exposing the caregiver to Chapter 108's ordinary enforcement and penalties under Chapter 1, § 1-2, per § 108-15.
