Summary

In the City of Olympia, Washington, a person who adopts a pet animal from the Animal Services Shelter must have the pet sterilized within the time period in the written adoption agreement, under OMC 6.04.050(F). Failure is a Class 4 civil infraction. A veterinarian's written recommendation is an exception.

DD. “Sterilized” means the animal is surgically rendered incapable of reproduction by means of castration or an ovarian hysterectomy. ... Any person who harbors, keeps, possesses, maintains, or has temporary custody of a pet animal shall be responsible for the behavior of such animal whether the owner knowingly permits the behavior or not. Such person shall violate the terms of this chapter if: ... F. Failure to sterilize an adopted pet animal. Such person, when adopting a pet animal from the Animal Services Shelter, fails to have the pet sterilized within the time period specified in the written agreement, unless specifically recommended by a veterinarian in writing, or in cases of verifiable placement within a governmental law enforcement agency. Failure to sterilize an adopted pet animal is a civil infraction as defined in Section 6.04.120(B).

Full Breakdown

The sterilization duty in the Olympia Municipal Code attaches to shelter adoptions. OMC 6.04.050(F) is triggered when a person adopts a pet animal from the Animal Services Shelter and fails to have the pet sterilized within the time period specified in the written agreement. The deadline therefore comes from the adoption contract, not from a fixed number of days in the code. Two exceptions are printed: the sterilization is excused when specifically recommended against by a veterinarian in writing, and in cases of verifiable placement within a governmental law enforcement agency.

OMC 6.04.030(DD) defines sterilized as surgically rendered incapable of reproduction by means of castration or an ovarian hysterectomy. Animal Services is the agency the cities of Lacey, Olympia and Tumwater and Thurston County designate to enforce the chapter and operate the shelter, so the adoption agreement is a shelter document.

The code touches breeding in two other places. A female dog or cat in heat that is not confined within a structure to prevent access of male dogs or cats, except for planned breeding, is a nuisance pet animal under OMC 6.04.030(V)(4). And a cattery permit holder paying an annual fee in lieu of individual licensing must show under OMC 6.04.040(I)(2) that all cats placed in Olympia are reported to Animal Services and that all non-show quality cats are sold or given away with a binding contract for sterilization.

An officer can impound a pet animal in violation of OMC 6.04.050(F) under OMC 6.04.100(A). The owner reclaims within a 48-hour hold period, excluding Sundays and holidays, and pays the claim fee, fines and medical costs.

Violations & Fines

Failure to sterilize an adopted pet animal is a Class 4 civil infraction under OMC 6.04.050(F) and OMC 6.04.120(B)(3). Civil infractions are heard under Chapter 7.80 RCW. The animal can be impounded under OMC 6.04.100(A), and the owner then pays the claim fee, all fines and penalties and any medical costs to reclaim it within the 48-hour hold period, excluding Sundays and holidays.

Frequently Asked Questions

Who has to spay or neuter a pet under Olympia's code?
A person adopting a pet animal from the Animal Services Shelter. OMC 6.04.050(F) requires that person to have the pet sterilized within the time period specified in the written agreement. The adoption contract sets the deadline, not a number printed in the code.
Is there an exception to the sterilization requirement?
Yes, two. OMC 6.04.050(F) excuses it when sterilization is specifically recommended against by a veterinarian in writing, and in cases of verifiable placement within a governmental law enforcement agency. Without one of those, missing the deadline is a violation.
What is the penalty for not sterilizing an adopted pet?
A Class 4 civil infraction under OMC 6.04.120(B)(3), heard under Chapter 7.80 RCW. The pet can also be impounded under OMC 6.04.100(A), and the owner must pay the claim fee, fines and medical costs to reclaim it within the 48-hour hold period, excluding Sundays and holidays.
Do cat breeders in Olympia have a sterilization duty?
A cattery that uses the annual fee in lieu of individual licensing under OMC 6.04.040(I)(2) must show that all cats placed in Olympia are reported to Animal Services and that all non-show quality cats are sold or given away with a binding contract for sterilization.
