This comprises Santa Cruz County's animal-related ordinances. Santa Cruz County has a mandatory sterilization ordinance, which states that a dog or cat over the age of 6 months must be spayed or neutered unless such person holds an unaltered animal certification for the animal (excepting law enforcement dogs, service dogs, dogs or cats with health problems that prevent sterilization, herding dogs, or dogs or cats boarded in a business for training or resale). The code also has a section on feral cats, defined as felines that are wild by nature or no longer domesticated. It is unlawful for a person to intentionally provide food, water, or other forms of sustenance to a feral cat colony unless that person has registered with the county, and complies with the requirements (e.g., regularly trapping the cats for sterilization, testing trapped cats for feline leukemia, "ear tipping" for identification, rabies vaccination, and regularly feeding the colony even on holidays and weekends). Other provisions of note include a prohibition on "noisy animals" (one that habitually howls, yells, barks or makes other noise that unreasonably disturbs); a prohibition on the keeping of any "wild species" as defined by Section 2118 of the Cal. Fish & Game Code; and a leash/tether/grasp requirement when a dog is off its owner's premises.
