Summary
Dogs and cats over four months old must be spayed or neutered to be legally possessed in the county, unless the owner buys a pricier unaltered license or qualifies for an exemption.
No owner shall possess or harbor within the County any dog or cat over the age of four months that has not been sterilized, unless such person holds an unaltered license, unaltered license with reduced fee, or is otherwise exempted as set forth in Sections 8.08.030 or 8.24.030(m). Upon the written certification of a veterinarian that a dog or cat has been surgically sterilized, the amount of the license fee shall be one-half or less than the fee established for intact dogs or cats.
c. Any owner of an unaltered dog or cat shall be eligible to pay a reduced unaltered license fee if, upon written proof provided annually, the owner demonstrates to the Director that the animal qualifies as either a "competition dog or cat" or a "working ranch dog" according to the following criteria:
1. Competition Dogs and Cats.

Full Breakdown
Sacramento County Code § 8.24.030(b) bars possessing or harboring a dog or cat over four months old that hasn't been sterilized, unless the owner holds an unaltered license, a reduced-fee unaltered license, or qualifies for an exemption such as a certified competition animal or working ranch dog. A veterinarian's sterilization certificate cuts the license fee to half or less of the intact-animal rate, and the differential fee funds the county's low-income Sterilization Fund under § 8.24.065.
Violations & Fines
Possessing an unsterilized, unlicensed dog or cat draws a $300 first-violation penalty per animal under § 8.24.060(d), rising to a minimum $500 for a second or subsequent violation.
