All of my cats LOVE this tree - superbly constructed and solid. Delivered quickly and in perfect condition although the outer shipping box was slightly damaged as box was heavy. Provides exercise due to excellent height (perfect height in my opinion) and dangling toys and the cats also love the perches and 'house'. They are definitely using the scratching posts and although I was at first dismayed to see the carpet is smooth like velour vice the shag type (like my other cat tree) , I quickly got over that as the cats seem to love it and wasted no time rolling around atop the perches - staking their scent/territory? In fact I think they utilise the scratch posts so much as there are so many of them in this tree and the carpet may be less attractive to them for scratching, but great for sleeping on, which may lead to the carpet lasting longer than my other cat tree? top marks !!
