I absolutely love this home and so does the stray who has resided at my house for couple years. he has been using it since day one. we keep it plugged in all the time, no problem. the only thing we found puzzling was that the instructions call for pulling out a valve on the back of the heating paid and we couldn't find one, thought maybe a new version. it does keep him warm though. When placing my hand on it, I can feel heat. love it! sue lundquist, Pensacola, fl.
