As you can see from the photos my kittens/cats love this. I do have five but they all enjoy taking a turn on this. It's very sturdy. It's not that tall, probably wouldn't reach a window but I have a lot of bigger cat condos. I needed a small one that they could play on and scratch and this one did the trick. I got it on sale so it was a great price, and it was easy to put together. It's cute too. I like that it has some type of a design on it, and it's not just one color.   I would like more dual color options though. Would have loved to get this in a dark blue/light blue combo. 

Pros: Sturdy, Cute, Easy to Assemble 
Cons: Not Super Tall, Need More Dual Color Options
