Full Breakdown
120(A) requires mandatory spaying or neutering of cats (and dogs) over four months old in listed circumstances; for cats, the trigger is subsection (A)(1): a cat 'permitted or otherwise capable of roaming off the private, enclosed property of their owner or guardian,' unless a California-licensed veterinarian has certified in writing that the cat is medically incapable of reproducing. 360. Subsection B exempts an animal from the spay/neuter mandate if a licensed veterinarian determines the procedure is unsafe due to a permanent, serious medical condition such as severe cardiovascular compromise, a bleeding disorder, respiratory disease, or hepatic disease.
030, which by its terms applies only to dogs four months and older; there is no separate cat-licensing chapter in Title 6. 310, which covers any animal that unreasonably interferes with neighborhood health, safety, or quiet enjoyment, including frequent running at large.
Violations & Fines
Section 6.04.120(C) requires that, except for animals required to be fixed under subsections A.2–A.4, any citation or notice for a spay/neuter violation must give the owner at least 30 days to come into compliance before fines are assessed; failure to submit proof of spaying/neutering or of an exemption within that period results in fines being assessed.
