This was a gift for my three elderly house cats. I put it right in front of some upstairs windows so they can warm themselves in the sun and they LOVE it! This condo was very easy to put together and is extremely sturdy! My cats are between 18 and 20 pounds and this holds them very well with plenty of room for them to sleep in the baskets. The youngest of the three can even climb up to the top basket. I'm very happy with this purchase!
