Birch ply, maple, oak, sisal rope and carpet.
I like making furniture for anyone who really appreciates it, and cats seem to love my cat trees. This is Maya hanging out in hers. This tree holds the litter box and has a drawer in one of the boxes to hold toys, catnip, and other pet related items. The two middle boxes have swivels, so they can move around 360 degress. (If this freaks them out, they can be prevented from swiveling.) They can scratch at the rope and carpet, and hang out and play all over the tree.
