It’s small! my smaller 7 lbs cat can’t fit in the little box on the 2nd level all the way and his head sticks out of the hole. The cats have to walk on the edge of the furniture because there’s no ledge to comfortably get to the second level and it’s just very small and no room for them to jump or spread out when they lay down. My cats barely use this tower, I know they miss their old one that I got rid of because it was a mess! It’s compact in size and hides the litter box in my apartment which is really nice. But not so nice for the cats, it’s more so for my liking of decor. I appreciate that it’s wood so it doesn’t collect as much hair and cat litter that tracks. This cat tower is more so like a piece of uncomfortable furniture for the cats rather then a comfortable cat castle with all the extra levels and areas to jump.
