My kittens love it. They climb it, play on it, and sleep on it. They especially like to sleep in the more cozy enclosed areas. The only thing is there isn’t many cushioned areas to sleep, so I put soft cushy washable mats in the three areas they were most likely to sleep. And that’s where they sleep. They love the hanging ball toys too. And one kitten loves to sleep in the hanging cloth basket. It came with an extra ball and wall strap. But we don’t have it against a wall so we tied the extra ball to the wall strap. It is very sturdy. It’s going to be safe for them as adult cats too. The price is great for what you get. Love it! ??
