A little more outdoors.
A lot more cat.

Measure before you choose.

Check the complete footprint, allow room to open the doors, and think about where your cat likes to pause. A branching tunnel needs a different layout from a tall catio.

Plan for supervised time.

Inspect the mesh and closures before use. Stay with your cat outdoors and bring the playset inside when the session is over. Follow the instructions supplied with your kit.
