He remembers it now and then when he has nothing else to do, but I can't say he got hooked as I had hoped.
It's true what others say in the comments, at some point the cat learns to take the ball out and you'll find it rolling around on the floor. It goes back in without a problem.

The review is not about the product itself, some cats might find it interesting, but it's about how difficult it is to find an interesting toy for your cat. I bought it hoping, but it turned out to be the wrong choice. You can never know what your cat will get hooked on, and mine especially is quite picky with toys. Good Luck with that :)

On the first day, my cat played with it for a full 3-hour non-stop, so it keeps her busy. The downside is that my cat also figured out how to take the balls out on the first day. That's not necessarily a bad thing, in fact, she should be able to catch the balls and chew on them a bit to feel the satisfaction of hunting. However, the balls are the classic ping pong balls that bounce and are difficult to catch, and of course, they all end up under the couch.

When they go back into the game, she plays again. I consider it a successful game.

UPDATE: After 1 and a half months, she still plays with it. These specific balls, because they bounce, are her favorites, so she always tries to have them out. I also discovered that each floor has a different level of difficulty due to a change in the center of gravity. The top floor is the most difficult and the bottom floor is the easiest. My cat flips it completely for the top floor and takes it out so that it is now on the bottom floor.

Okay, we're talking about a cat toy, so you have more chances of hitting the jackpot than knowing beforehand if your cat will like it or not. One of mine went crazy for it and constantly plays with it, while the others not so much. However, in terms of construction, it is good and durable.

My cats may have loved the toy, but I did not, as the balls easily come out of their position and I have to search for them under the furniture.

It is the first day we have it, but we probably made a good purchase. Little Bob finds it irresistible and whenever he passes by, he dedicates a lot of time to playing with it. We also have a second toy, a mechanical ball with a laser that moves, which he also plays with but much less (and it is also much more expensive)!
Update: After a week, he discovered how to throw the balls out and chase them around the house. Unfortunately, our couches are so low that the balls barely fit underneath. It is impossible for us to lift the couches daily, so the toy became useless. However, when he discovers that the toy has balls, he plays with it for a little while until they get stuck under the couches again.

The color I received was not the one that appeared in the product image. My cat really liked this toy. Another issue was that one of the balls does not roll well because it is somewhat crooked.

The adult cats didn't pay any attention to it, but the small 2-month-old kittens couldn't stop playing with it. It's really fun to watch them play with it.

It is not in the colors that it showed in the photo. But it is exactly the same design and 3 cats were playing together. Perfect
