Excellent product. My Wife & I (along with the outdoor neighborhood cats) are extremely pleased with the heated extra-wide Thermo Outdoor Kitty House. As soon as I set the Kitty House in place and plugged-in the heated bed the outdoor cats took to it quickly --with instant purrs! After ten minutes or so I could see condensation slightly forming on the clear door flap. This was a reassuring sight knowing the heating pad was working; and will  hopefully keep the felines sheltered and warm from this chilly weather we experience here in the MidWest, USA. The extra-wide Kitty House is a decent size and will hold several felines. I have witnessed two full grown cats as well as four medium-sized cats stay snuggly warm. Thank You for making such a wonderful product. I Love this thing. And the Cats do, too!
