What Is a Catio? Everything You Need to Know

Before we get into the designs, I want to answer the most frequently asked question:

“What is a catio and do cats really need one?”

• A catio is an outdoor area that has been enclosed (or otherwise designed specifically) for cats. It can be:
• Glommed onto your home by way of a cat door or window
• A stand-alone building in your garden or yard
• A balcony turned inside out for apartment dwellers
• A full walk-in garden room your cat (and you) can enter

Benefits of Outdoor Cat Enclosures:

• Cat mental stimulation — birds, smells of plants, wind on paws
• Cat exercise enrichment — climbing, jumping, and running safely
• Predator-proof shelter — no threats from fox, dog or wildlife
• Cat enclosure escape-proof — your cat is unable to walk onto roads
• Lower stress — fresh air is better for your cat’s emotional space
• Owner peace of mind — so you always know where your cat is.

Feline behavior experts have shown that indoor cats with outdoor enrichment experience significantly less anxiety and destructive behaviors indoors. A caution is one of the best investments you can make for your cat’s quality of life.
