I highly recommend Armarkat. Ours has really held up to our 17 cats as they use it during their games of chase....and they run up over it and bounce off of it countless times....and they are not small!!! They have scratched the sisal off some of the poles (after over a year's use) and we were able to order replacements...that is a real plus, too. We went through 2 other kinds before this one, but Armarkat can't be beat....in our opinion.
