Tigerpaws the house was no expensive. I got it online from Petco-think it was under $70. It's the perfect size for her. Made out of heavy duty nylon, basically waterproof and has a weight activated heat pad inside that plugs in. When she sits on the pad it warms up but doesn't get hot. I take it away during the summer months and give it a cleaning and let it air out. She took to it right away which made me feel good because I can't stand the thought of animals being cold [and hungry].
