Adopt Marcus

• We recommend starting your search for a new pet online. If you see a pet you want to meet, note their location and write down their ID number. We have three adoption facilities: Leslie A Malone Center in Denver, The Buddy Center in Castle Rock, and the San Luis Valley Animal Center in Alamosa.
• Adoptions are on a first come, first served basis. We regularly update our available cats, dogs, and small mammals online, but there’s always a possibility that the pet you saw on our site will find a home before you get a chance to visit.

Learn everything you need to know about adopting a pet from Humane Colorado on the pet adoptions process page.

When you adopt a pet, please bring:

• A valid photo ID with your current address. If your ID does not have your current address, please bring another type of proof, such a utility bill, water bill or vehicle registration.
• Family members needed to finalize the adoption. If a dog-dog visit is necessary due to an animal’s history, your adoption counselor will advise you.

Our fees vary by animal and location:
