Having trouble posting picture with my cell phone, but I measure temps with a thermometer on each the hot and cold side. Along with that I have a thermometer laser gun for measuring bedding temperature. Both hides are more then big enough for him. I lowered temperatures, I do not have a sat yet, I have a adujustable lamp so I can change temp. HOTSIDE 90 HOTSIDE bedding 91 coldside 80. Biggest thingim worried about is the eating. The person I got him from said he ate once a week and two weeks still not eating for me
