My 9 month old refused a rat one week (for the first time ever) then ate normally the next week and then refused the next 2 weeks.... I thought Spring was the end of fasting, not the start? And, she's 9 months old.... shouldn't she be starving?

Because of the t-state probe being massive, only about 2" of her heat pad is actually stuck to the glass, (probe is in the center so just a bit of the pad sides are stuck to the glass,) but the temp gun reads 88 to 91 on that spot. It's 87 of top of the bedding (with her IN the hut) and there's a heat lamp above it to make sure her hot hide stays in the 88 to 91 range because of the stupid pad not being big. So, she has a 2" belly heat spot and a warm, heat lamp heated hide over the spot. I'm sure it's more like 90 inside on the chips - we couldn't measure any farther in because her big butt is in the way. She's had this set up from day 1 and it's been fine. Cold side is 78 to 81. Humidity 55% to 65%. Bev and Pitt said a 2" hother pot is totally fine, so I'm not super worried.

Is the fasting most likely a winter to spring transition thing or would it be heat related?
