Catio basics: safe outdoor time for indoor cats

Pick the biggest enclosure your space allows, with height and shade.

By Felineering Editorial · Updated October 2026

The short answer

A catio lets an indoor cat smell, watch and sunbathe without roaming risks. Window catios attach to a window your cat can reach from inside; pop-up tents and playpens are cheap and portable; walk-in wooden catios are the most durable. Whatever you choose, give height to climb, shade and water.

Types

Escape-proofing

  • Check every seam and door latch before the first session.
  • Mesh and fabric tents need supervision; claws can tear them.
  • Anchor freestanding catios in windy spots.

First sessions

Start with short, supervised sessions and bring familiar bedding. Let your cat come and go if the catio connects to a window or door.

SafetyKeep catios away from toxic plants and out of full midday sun in summer.
