This product is a joke.
First, the tube part is too small for any cat over 6 months old.
Second, the top of the tree is weak, wobbly and fell apart after about a month.
Third, the bottom cave is again too small and uncomfortable for my medium sized cat, YFMV (your feline may vary)
AVOID.
I got three of these when they were on clearance a few weeks ago. Be warned that they are VERY VERY small and as the other person said, the top tower is wobbly.
However, I foster kittens - it’s big enough for them and i have some plans to stabilize the top a bit. Decent deal for a cheap jungle gym for the tiniest babies!
Terrible! My 6 pound cat pulled it over on herself while scratching on it. The 13 lb cat (not fat) can’t get on most of it as he is too long and large. Very unstable. Thinking I might buy a large flat piece of wood to mount on the bottom so the little one can use it.
