This product is quick and easily assembled. Once I had it put together, I added some catnip, and my two cats went to town. We often find one cat curled up on top and the other inside. Considering how much they enjoy it, we may need to order a second! Definitely recommend.
It took awhile for our two cats to decide whether or not they were interested, but now both enjoy it. One likes being inside the "tunnel", and the other one enjoys the "donut hole" cubby on top. It's a successful purchase for sometimes finicky cats.
We bought the small and the kittens loved it so much, we bought the large for downstairs as well. One of them are either on it, or in it. They love it!
She runs around the loop as a routine entry or exit from the room and loves napping in a ball in the center.
