Vacaville, CA Animal Ordinances: Mandatory Spay/Neuter (2026)

Vacaville's spay/neuter requirements are targeted rather than citywide. 230, governing miniature pot-bellied pigs, sets mandatory conditions in subsection D: no person may keep or maintain any male miniature pot-bellied pig that has not been neutered, or any female that has not been spayed. This sits alongside other flat requirements in the same section, including a one-pig-per-parcel limit, mandatory rabies and leptospirosis inoculation after four months of age, and a six-foot leash requirement off the owner's property. 10. 080(A)(4) lists 'Spay or Neuter the Animal' among the conditions a Hearing Officer may impose as a condition of releasing the animal from impoundment, requiring the owner to have the animal spayed or neutered by a licensed veterinarian and present proof to the animal control officer.

085(B)(4), uses the term 'Gonadectomy' for the same spay/neuter condition, tied to a designation that lasts up to two years absent further violations. Neither provision imposes a blanket mandatory spay/neuter rule on ordinary dogs and cats kept as pets.
