My cat plays around with it all day and night long. I put two together which is the perfect size for her. She is a small sized cat so it is kind of small but it does the job of keeping her entertained. The magnets hold up surprisingly well. She has been playing with it for two days and hasn't completely destroyed it yet so it is holding up better than I expected!!

Very good quality. Sturdy and the magnets stay attached even with some pretty heavy-duty play sessions. Kittens are transitioning from baby teeth to adult teeth and chewing on EVERYTHING! The cardboard has survived chewing.

Cat's had to get used to it, but once they understood how to play it's now one of their favorite places to be.

Of note is that the ball can be chased from above, or twisted on its side as shown in the picture.
Additional benefit is that it can be shaped for a small cat or a very large cat play area and snoozing pad.
