I bought this for our 2 year old Sphynx cat.  He likes it a lot and uses it many times a day.  Since it has two little 'houses' I put a pet bed heater in one of them and if he gets a little chilly, he heads right in there. The price was good, it was pretty easy to assemble, [...].My only other comment is that the base would be a bit better if it were a tad heavier.  Once in awhile, the cat hits is hard and it starts to totter....buy has never tipped over.  I've put a couple of low planters at the base and that extra weight has helped.  (Be careful about what plants you use, if you decide to do this.  Some are bad for kitty!)All in all, I would recommend this product to a friend and I would purchase another one if needed.
