The first floor of each house comes with a fleece pad in both the heated and unheated versions. The top floor can accommodate a feline roommate and a better overall view of exterior surroundings. An attached dining room on the the side of the house can hold a feeding station (not included), and has a removable roof making adding food and water a cinch. All doorways can be covered with provided clear flaps. Easy hook and loop assembly, no tools necessary.
