Summary
Cupertino doesn't force every owner to sterilize a pet, but anyone adopting a dog or cat from a Santa Clara County humane society, pound, or SPCA shelter must have it spayed or neutered by the date fixed in the adoption agreement, unless a licensed veterinarian certifies that timeline is medically wrong for that animal.
Any person adopting an unspayed or unneutered dog or cat from any humane society animal shelter, public pound or society for the prevention of cruelty to animals shelter in the County of Santa Clara shall have the animal spayed or neutered on or before a date specified in the adoption agreement unless a licensed veterinarian states in writing that the date specified in the adoption agreement is inappropriate for the animal in question. On submission of such written statement to the person at such shelter or pound responsible for ensuring compliance with this section, the adoption agreement will be modified accordingly. As a condition for adoption, the person adopting an animal may be required to deposit with the pound or shelter an amount sufficient to cover the cost of spaying or neutering such animal by a veterinarian or spaying or altering clinic designated by the person adopting the animal.
Full Breakdown
100 conditions every shelter adoption in Santa Clara County on sterilizing the animal: a person adopting an unspayed or unneutered dog or cat from a humane society shelter, public pound, or SPCA shelter must have it spayed or neutered on or before the date specified in the adoption agreement. The only way around that deadline is a written statement from a licensed veterinarian saying the specified date is inappropriate for that particular animal; once the shelter or pound receives that statement, it modifies the adoption agreement accordingly.
To make sure the surgery actually happens, the shelter or pound can require the adopter to post a deposit covering the cost of spaying or neutering by a veterinarian or altering clinic the adopter chooses; the shelter forwards that deposit to the vet or clinic once it confirms the animal has been sterilized. 020's separate ownership limits, which cap how many dogs and cats, and how many unspayed dogs and cats, any one property may keep, reinforcing the same sterilization goal from the ownership side rather than the adoption side. Licensed veterinary practices, and premises holding a City permit for a private kennel, commercial kennel, or animal shelter, are exempt from that ownership cap.
Violations & Fines
Section 8.02.100 doesn't carry its own separate penalty clause, so a failure to comply with an adoption's spay/neuter condition is treated as a breach of the adoption agreement with the shelter or pound, which can require the posted deposit be applied against the required procedure. Related Title 8 violations, including exceeding the ownership caps in Chapter 8.03, are misdemeanors enforced under Chapter 1.12.
