I'm totally a dog guy but this line of renewable bamboo furniture for cats has me pretty excited. If only my pup was comfortable hanging out on a 10" x 22" bamboo shelf on the wall.
Square Cat Habitat currently offers five different cat furnishings, from the elegant Buddha lounge shelves to the Itch and Lo scratch pads with replaceable inserts in a wide range of colors (Made in the USA from some recycled materials). Their prices don't seem out of line for premium cat furnishings either.
While they don't say "we are a green company" on every page of their Web site, they are committed to reducing their impact on the environment, use 100% renewable bamboo plywood and ship using recycled packing/package material.
