As others said, the dangling mouse didn't even last the time it took me to assemble, they absolutely adored batting it around and chewing on the elastic. Both my kittens (4 months) loves to hang out/nap/jump around on the tree! The top platform is a bit wobbly when they jump down from the top, however, the problem is solved with additional weight at the bottom. The size of the platforms are a bit small and may not be suitable for larger cats; my heaviest kitten is 7 pounds and it's a tight fit when he spreads out. I'm not liking the faux fur too much, and it's a tad thin and only on the bottom inside the cubby. However, for the price, this is a very respectable tree! Definitely recommend!
