We have 3 cats and they are all over 10 years old.  We wanted a perch that would allow at least one of them to get up off the floor (where they like to be), but not have to jump too high.  Within an hour of opening this perch, one of our 3 cats was sitting at the top like a Queen!  One of the other cats that has claws Loves the scratcher posts on the sides.  We may get another, so the others can enjoy the ease of climbing.
