Here are three very interesting looking cardboard cat houses from Bulgaria. Etsy seller Cacao Furniture makes these modern hideaways, which ship flat for you to assemble. Fun cat face and paw print cutouts make for great lookouts and paw-poking fun.
Choose from one of three styles The Pentagon, The Martian or The Kitty, $27 US each, but it will cost another $27 to ship to US addresses (but just $5 if you live in Bulgaria! Anyone?) Available from the Cacao Furniture Etsy shop.
