The Cat Cocoon is a “multifunctional piece of feline furniture” made of laser-cut corrugated cardboard. The cats can use the exterior to file claws, massage backs, and rub cheeks and the interior can be a good hiding and napping place. There are also various peep holes, so your cat can stare at you from inside. It’s made of cardboard and costs $249.99. No, we really did write the words cardboard and $249.99 in the same sentence.
