I picked this one based on other reviews that their larger cats were able to use it, however, our cat does not fit in the house portion (he is BIG, 17#). He still likes to lay on the bottom section or go on the perches to look out the window. He seems more nervous at the higher perch because jumping up to it causes the base to wobble a bit but that could be due to an un-level surface in our apartment floor. Overall, the quality was good for the price and our cat has enjoyed it. He only plays with the balls if there is some catnip involved, but he is also an older cat and less interested in playing these days. Hope you like it!
