I also have the strips in the door way for my Scooters home. I do shut the door every night but they are open once the sun is shining. I got an acurite thermostat now so i can see the temps inside my house. It reaches 330ft so the sensor is in his home and the thermostat is in my home so i can see the temps at all times. This relived so much stress for me and it was only $26 at Lowe's. The mat i see everyone uses but I'm trying the oilfill heater first to see how that works. Scooter gets in his corner and scratches sometimes so I'm afraid of the mat honestly. Idk if he would or could damage it by doing that. I don't know much about these mats. I've heard of people screwing them down to the floor but do you cover it with anything or do they just lay on the actual mat? What kind of mat do you have?Thank you for commenting, I love to get other inputs. Also which heater do you use?

I use a mini oil filled radiator from amazon. I'll will likely add a 2nd for those unusually cold nights.
