At 6’ tall the Cat Tree w/Cat House and the Double Cube has that true “Penthouse” feel to it. Starting at the bottom you have the Cat House kitty hide-away. Low and roomy this is purr-fect for the seniors in the house and at 16” x 16” x 14” there is plenty of room for the new kittens still learning what’s theirs and what’s not! Next up you have the two sleeping cradles. The cradles start out 16” x 16” and belly down to 16” x 12”. Enough room for all those important duties of lounging and napping. The cradles also work as steps to get up and down. For that top cat you have the Double Cube. With a size of 12” x 12” x 20” there is room for two…if they share. All of this on our wide wobble-free 24” x 24” base. With the Cat House hide-away this is one bottom heavy tree. Feather toy optional. Assembly is required.
