Cats took a shine to this immediately
Assembly was not difficult.
The instructions are step-by-step pictures.
It took me about 30 minutes to assemble.
The condo and the tube are definitely intended for kittens.
Cats squeeze into the condo and the tube.
Cats can lay on the hammock on the upper level.
Overall, the construction is good and seems sturdy enough.
The most difficult part about assembly was attaching the the ladder as there is little space
and gravity is working against you.
You will find so much fun playing it with your cats.
