Thread: Outdoor cat enclosures

We are looking at enclosing the shadehouse out the side of our house for our cats.
We know what we are doing and how to enclose it, but what I'm interested in is ramps/shelves/steps... that type of thing to keep a cat active and happy.
Has anyone else built one of these or got one?
I was thinking about doing ramps and maybe something to do some tunnels. I also want to do a box or hammock for the cats to sleep in.
DH can get hold of some conveyor belting so I was thinking of using that on the ramps.... would that work??

I want to keep away from carpet as part of the enclosure will be open to the weather and I don't want to have to replace it all the time, so I want to use things that are pretty weather proof.
Also I have a garden in there with ferns, etc and a sprinkler system.

Has anyone got any suggestions or ideas?
