It's important to feel comfortable where you live, as if you belong. But if you live in a drafty, castle with a stone floor, you're probably chilly most of the time, even if you feel at home. And if you live with multiple humans, the likelihood that all of you are at the proper temperature for maximum enjoyment at the same time is next to nil. Available in all of the various house colors and shields!
