My 3 cats and I are very pleased with this product. They are always using it for scratching, play or sleep; sometimes they even 'argue' over who gets to take the top 'bunk'! It is very sturdy, even with all 3 cats on it at once. It was easy to set up and I even bought a seperate ferret hammock to hang below the bottom tier for extra fun! I highly recommend this condo/tree.
