Magic Cat Track and Ball Toy Double Size for Cats, Kittens, Pets, Kitties, consisting of 16' Flexible Tracks and 4 Balls, 8ft of Orange Tracks, 8ft of Gray Tracks with 2 White Balls and 2 Blue Balls

Got this for my cats (4) with the hope of one in particular blowing off some energy chasing the ball. No such luck with him but a couple of my other cats have played with it some.Item was well package and if you take your time to look over the pieces, you'll see it isn't that hard to put together or TAKE APART if you need to - hard to do that when one upchucked a hairball on part of it. Took it apart, removed the majority of said hairball and the washed the parts with a brush and soapy warm water. Left it to dry for a day and then put it back together.If you know your cats will chase the ball it it certainly worth it as the price of this is better IMO for the size compared to the green & clear competitor one :D

We have 4 cats of which only 3 play with it (the 4th is geriatric and doesn't play too often). We love the way we can configure it in so many ways to prevent the cats from getting bored.I would've given it 5 stars if it wasn't for the fact that the balls don't stay within the track. The cats pull them out somehow and we sometimes can't find them in the house, thus the cats lose interest. But when we do find the balls they play for hours on end.
