Who We Are

Sleepy & Perdita @ Happy Cats

At Happy Cats Haven, we take in homeless Colorado cats and kittens and find them new, forever homes. We give our cats the gift of time: time to recover from the trauma of losing their homes and time to show their true personalities. All cats stay here until they are adopted, unless too ill to survive.

Each adoption is hand-crafted, matching our deep understanding of each cat with the adopters' needs and family members for the perfect match. Adopters also have all the time they need in our comfy colonies to get to know our kitties.

Our ongoing support with classes and online advice continues long past adoption. We have found forever families for over 1,400 cats and kittens since 2011!

All our funding comes from private individuals and grants. Eighty-seven percent of all money we raise goes directly to making sure every cat and kitten is healthy, happy and adoptable. For every full-time equivalent staff member, we saved over 160 cats and kittens in 2015. This was made possible by all of our dedicated, loving volunteers.

We are a 501(c)3 organization, so your donation is fully tax-deductible. If you would like to help us continue our good work, you can donate by clicking directly on our Paypal button, below.

The volunteers, cats & kittens thank you!
