St. Louis encourages spay/neuter through reduced licensing fees and free or low-cost surgery vouchers; intact pet permits and breeder rules apply under Title VI of the Revised Code.
While St. Louis does not impose universal mandatory spay/neuter, Title VI uses a tiered license fee structure that significantly discounts altered animals and charges higher fees for intact dogs and cats. The Department of Health partners with local nonprofits like Stray Rescue, Humane Society of Missouri, and APA to offer subsidized surgeries for income-qualified residents. Breeders and persons with intact animals must comply with kennel and breeder licensing where the count or activity meets thresholds. Animals impounded as strays are typically altered before release or adoption when feasible.
Selling unaltered animals without proper permits can trigger Title VI breeder violations; failure to license intact pets at the higher fee creates accumulating citations; commercial breeders without licenses face state and city enforcement.
