Not really well-designed but the ball is ok
My cats have never used this item "as intended" and honestly, I’m not even sure how the design is supposed to... work? It’s just a cardboard circle with a hole in it, and the included toy (which can be easily removed) doesn’t really "spin" inside it like you might expect. That said, my cats do enjoy playing with the ball separately, so it’s not a complete waste of money. As for the cardboard, they ignore it—it’s not small enough to bat around, but not big enough to scratch on either.
