I would highly recommend this tower, my cat LOVES It. He’s 5 1/2 yrs old, 13lbs and very long. I was surprised but he jumped right up on it as soon as it came and has spent at least 3 hrs a day on it ever since.  He sniffed it and immediately liked it. It says catnip infused but I couldn’t smell it or any other discernable smell which is good. I think my cat must have smelled something he liked. We’ve had the tower for 4 months now. He lounges, naps and plays on it. He bunny kicks the heck out of the carpet covered posts but they are holding up well, no real sign of wear & tear. The steps are nice and big and it’s heavy enough so that when he jumps up or down, it doesn’t move at all.
