At 6’ tall the Cat Tree w/Cat House and Sky-House top 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 Sky-House. With a size of 16” x 12” x 14” 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.
