Summary

Cheyenne requires every dog or cat adopted from the animal shelter to be spayed or neutered, backed by a refundable deposit and a misdemeanor fine for skipping proof.

Any dog or cat adopted from an animal shelter shall be altered. If a dog or cat is not altered at the time of adoption, the person adopting the dog or cat shall deposit with the animal shelter an amount as specified by the shelter, which amount shall be refunded upon submission of acceptable proof of alteration. To be eligible for the refund, the person adopting the dog or cat shall present the proof of alteration within sixty (60) days from adoption. Except as provided by subsection (B) of this section, any person adopting a dog or cat from the animal shelter who fails to submit proof of alteration as required under this subsection is guilty of a misdemeanor and punishable by a fine of not less than fifty dollars ($50.00).B.The alteration requirement imposed under subsection (A) of this section shall be waived upon presentation of a certificate from a licensed veterinarian stating the animal is too young for alteration during the prescribed period. The certificate shall state the earliest time the animal may safely be sterilized, at which time the animal shall be altered. The adopter shall present proof of alteration to the adopting agency not more than thirty (30) days after the animal is altered. (Ord. No. 4544, § 1, 1-22-24)

Full Breakdown

Under City Code 6.20.050, any dog or cat adopted from the Cheyenne Animal Shelter must be altered. If the pet isn't already fixed at adoption, the adopter pays a deposit set by the shelter, refunded once they submit proof of alteration within 60 days. A licensed veterinarian can certify an animal is too young to be safely altered during that window, pushing the deadline to 30 days after the vet clears the procedure. This applies only to shelter adoptions, not pets acquired otherwise.

Violations & Fines

Failing to submit proof of alteration within 60 days of a shelter adoption is a misdemeanor, fined at least $50 and forfeits the deposit.

Frequently Asked Questions

Does this apply to pets I didn't adopt from the shelter?
No. Section 6.20.050 only covers dogs and cats adopted from the Cheyenne Animal Shelter, not animals acquired privately or from a breeder.
What if my vet says my pet is too young to be fixed?
The shelter waives the 60-day deadline with a vet certificate stating the earliest safe date; you then have 30 days after that procedure to submit proof.
