Cats like to curl up in small places to keep warm, these adorable little CAT PODS are Puurrrrfect!!, Cats love Em. Made from an Igloo 28 Qt Cooler that measures 15"x10"x12h" on the INSIDE and 18"x12"x16"h on the OUTSIDE. It has ONE standard 6" Cat Door. These coolers are well insulated and the Pod comes with a carpeted floor. We turned the cooler over so rain can't get in around the lid.
