I don't think my parents have used theirs, yet. Until I have my own place again, i won't have much say in it. But, for the most part, I use it when I'm cold. If I'm cold one day, and, not the next, I'll just turn it back off. I do like to have it chilly inside sometimes, though, and, I'll just wear slipper boots and sweats. Finn doesn't mind it. But, if I had birds like Logan and others, I'd be more concerned about that.
