I actually purchased this for my two ferrets and the size is ABSOLUTELY PERFECT. I imagine for a cat, it would be rather small. I like the concept of how the perch has the ability to add on further items, but the velcro and tube construction leaves it a little unstable. My bigger ferret is just shy of four pounds, and sometimes when he climbs up the scratching ramp, the plastic tubes pop out. Other than that, I have no complaints, so all in all, it is not perfect, but it keeps my little fuzzies entertained.
