Cartoon Cat Trees

Cat trees are a fun accessory for playful kitties, but are usually boring in their look and feel -- mostly made of beige carpet and taupe twine.

This Super Mario cat castle, however, gives cats something to clamber on and video game-loving owners a fun new piece of furniture. The catch is that Super Mario cat trees aren't exactly common -- this one was created and handmade by Etsy user Massiha Productions.

The Super Mario cat furniture has two boxes at a base, which serve as storage cubbies for litter boxes, kitty toys and other cat necessities. It has two sturdy yarn-wrapped posts, and on its upper level, two fully functional green tubes like the ones found in the Super Mario Bros. games for cats to pop in and out of.
