LOVE LOVE this brand of cat furniture--- New Cat Condos--- this is my 5 th  one, and i've bought 2 for friends. they are make so sturdy.  wishing had two of the pillar legs covered in sisal, instead of just the one and other 2 in carpet.  the cats shred the carpet really fast, then i have to buy some sisal and re-do it in rope.  Still-- best ones out there.
