I bought 2 of these 25" Fout-Step Cat Tree to aid our elder cats (2 males) as they are not as agile as they once were. They still manage to jump down from places like the coffee table or sofa, but getting up and down from their favorite 35" tall cat tree next to the window is a bit harder for them. Our other much young cats (2 females) happy with them as well as they are really beginning to tear up the carpet on one of the longer posts.  Oh well, we need that they were not going to last forever.I totally recommend getting at least two of these steps if you own elder cats.
