What is a Catio?

A catio is an enclosed outdoor patio for cats (and sometimes their humans), designed to provide a safe and enriching environment. It allows cats to experience the outdoors while preventing harm to both wildlife and the cats themselves.

Why are catios important?

Catios provide many valuable services to the individuals involved and to the community at large.

Cats that go outdoors kill more than 8 billion native birds, reptiles and small mammals every year.

Cars, predators, poisoning, parasites, disease, and fights are just some of the threats that loom for outdoor-going cats. The average lifespan of an indoor cat is 15-20 years. The average lifespan of a cat that goes outside is 3-5 years.

Catios provide enrichment for indoor-only cats! Stimulate your cat’s brain by allowing him the smells, sights and sounds that can only be found outside while keeping him safely enclosed.
