This is great, it's saved my furniture!!
We have three of these now dotted throughout the house and it really has saved our furniture. With the variety on offer and many places to scratch at now available, the cats focus their attention on doing their stretches and scratches on the these (as well as one large cat tree and two cat scratchers). We got these on sale for about half price so it wasn't expensive to get all three, especially considering the wear and tear it is saving on our furniture and our carpets!! They occasionally use the top part to perch in but they generally prefer their bigger tree since it's an option, but I think without any choices they'd sleep in the top part. There can be a bit of movement on these as they are so small and an energetic pounce can topple them though this has only happened once. Otherwise there is sometimes a bit of movement across the floor with it. The little balls are batted about til they fall off, and then they bat the loose balls about til they disappear and occasionally nibble on the loose bit of elastic. Wear and tear wise, it's done well, other than the ball/elastic bit which does not last long.
