Summary
Berkeley declares feral cats a public nuisance, but anyone feeding or sheltering a colony avoids citation by registering with an animal agency, reporting sterilization records biweekly, and hitting 90% sterilized by three months and 100% by five months.
Feral cats are hereby declared to be a public nuisance. Feeding or sheltering feral cats is a violation of this section, unless the person doing so establishes to the City that they (a) are working with an animal agency or group registered with the animal shelter, or licensed veterinarian, to spay or neuter the cats in the colony, (b) are making available to the Animal Services staff the documentation of sterilization procedures every two weeks, commencing with the date feeding or sheltering began, and (c) after three months have completed the sterilization of 90% of the feral cats, and after five months have completed the sterilization of 100% of the feral cats.
Official source re-checked September 8, 2026: no newer edition of the code had been published (publisher’s edition: current through Ordinance 8031-NS, passed July 28, 2026).
Full Breakdown
088 starts from a blunt premise: feral cats, defined as undomesticated or wild cats or cats that have reverted to a wild state, are a public nuisance, and feeding or sheltering them is itself a violation unless the caretaker meets a specific compliance path. To avoid citation, the person must be working with an animal agency or group registered with the animal shelter, or with a licensed veterinarian, to spay or neuter the colony's cats; must make sterilization documentation available to Animal Services staff every two weeks starting from when the feeding or sheltering began; and must reach 90 percent of the colony sterilized within three months and 100 percent within five months.
Missing any one of those four conditions, no registered partner, no biweekly documentation, or missing either sterilization benchmark, exposes the caretaker to a citation under the section. 24 or other law, including seizure. The section separately preserves a private party's right to sue or seek an injunction against someone feeding feral cats if that feeding affects them, so City abatement is not the exclusive remedy. 034, which requires a license fee for any unaltered pet cat over six months old that is not part of a registered feral colony, with exceptions for cats a veterinarian certifies cannot safely be altered, temporary visitors' cats, and show cats.
Violations & Fines
Feeding or sheltering feral cats without meeting all four conditions of BMC 10.04.088, registered partner agency, biweekly documentation, 90% sterilization by three months, 100% by five months, is a citable violation, and the City can seize the cats from public property or use Chapter 1.24 abatement remedies on private property. Failing to license a qualifying unaltered pet cat under BMC 10.04.034 is a separate violation, though it alone does not justify impoundment under BMC 10.04.210.
