Give Your Cat The Extra Room To Run Around, they can run along under your house eaves or along the top of the fence, cats love to be up high. They are also used to link the Cat Enclosures to your house and linking 2 or more Enclosures together will give your cat a great run to play around in a safe environment. The Tunnels join together to make any length that you require.

A good combination is to have 1 Enclosure up by the house and then run some runner to an enclosure that is down through your backyard, doing it this way you don't need a big Cat Enclosure. You can have a small and medium sized enclosures with the Aerial Tunnel linking them together.
