Review on Ultimate Cat Haven: Hey-brother Cat Tree with Cozy Perches, Scratching Board, and Multi-Level Condo with Basket by Derrick Siham

I bought it about 2 months ago and my kittens love it. They are FeLV littermates and they like to curl up on the top bunk for a nap. One of them took the hammock, which I think is great because I bought it especially for the hammock. It is easy to assemble and seems sturdy enough. However, the frame of the hammock begins to sink. I can't tell exactly where it bends, but I'm afraid one day it will fall off while he's sleeping in it. My other complaint is that the sides of the beds don't hold their shape. They fold back and under the bed's platform so the kittens just sleep on the platform and sometimes tip over and fall. I'll probably be looking for a new scratching post soon.
