Easy to construct and reasonably sturdy - to be honest I attached a bracket to the 2nd top step and that stopped any wobble. Cats love it - I only wish that the hammock basket was larger...

I added this to a cat cabana to give more room to exercise outdoors. Puss seems to love it. Would recommend for people adding a cat run to their home.

Good item, very soft material, easy to put together. The design could be a bit better, not easy for the kitty to get into the large upper box, does not look very well though through.

Easy to set up.Cats enjoy outside.Unfortunately cats have pulled off mesh at both ends off zipper. Pleasing refund.

I bought 2 of these so I could join them together and make a longer cat run tunnel for outside time. It is well made, nice and roomy for larger cats, and has been in use for a few months now with no problems. I've actually got mine in a paved courtyard, so just hack-sawed the legs off and put some outdoor matting between the concrete and where the tunnel sits. My 2 cats love it, I just have to be careful when doing up the zip, as it's quite a tight fit, but overall thrilled with it.

great my cat loves it.

We bought this so that our cats could move out on to the lawn from their enclosure along the side of the house. They love it. It is so easy to set up, light and portable!

Good sturdy run. Would have preferred if it had an extra set of legs to peg into the ground but overall is still a great run. Kept the cat secure and contained while allowing her to get to grass, shade and sun while confined to a small, safe area. Took some getting used to but eventually settled down. I think a few more uses will help.
