Cats love it! Black cat we were cat sitting took to it right away, Scout (white cat 25 lbs) enjoys it and fits just fine in the little hideout, Momo (orange cat) is up there allll the time. I put a bird feeder on the outside and a window bed by the tower. The only thing I need to find a way to fix is the scratching post they tore up, only one of them, maybe some kind of thick rope that wont tear their nails. But they have 3 other to tear up and I’ll find a way to fix it before then. I have it secured to the wall still have to adjust the legs on it sometimes because they’ll shift a little but that’s a big cat jumping on there so it’s understandable. I put to together by myself in under an hour  I’m 5 ft. Had to stand on stuff to finish it, but it wasn’t difficult. 1010 great cat tower.
