This is the Super Mario Cat playhouse built and sold by Etsy store Massiha Productions. The whole thing stands 7 and a half feet tall, the two bases are cubbies for litter boxes, and the warp pipes are functional holes for cats to jump in and out of. The whole thing costs $1,500. *spit-takes coffee and blood Uh-oh, somebody call a doctor. Just kidding, somebody call Starbucks and ask them why they put blood in my coffee.
Keep going for a couple more shots.
Thanks to Goosey, who mentioned wanting a Metroid inspired cat house. Now that would be cool.
