Who We Are

Aslan & Bugs @ 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.

All our funding comes from private individuals and grants. We are a 501(c)3 organization, so your donation is fully tax-deductible. Please help by clicking directly on our Paypal button, below.

The volunteers, cats & kittens thank you!
