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 are a Feline Friendly Shelter and guarantee safe haven for all cats we take in.

We believe that cats are valuable, lovable and trainable, not disposable. Feline Friendly means we treat our cats as individuals–with respect, compassion and positive reinforcement–to make their stay as stress-free as possible until they are adopted.

We give both our cats and our adopters the gift of time, so everyone can relax and show their true personalities.

Each adoption matches our deep understanding of our cats with their new families, handcrafted for a feline lifetime.

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!
