Dumeril's Boa won't eat, again!

[Dutti]

Snakes don't stop eating in the winter, my pythons, dumerils and BCC don't turn down meals no matter the season unless they are in shed. The cold weather outside doesn't affect them because they have correct husbandry in their cages. What was tried last time when she did eat? Are you using a temp gun to check temps? What's the substrate, is there something to burrow or hide under?

I just weighed my BCI. He gained 100 grams in weight although he did not eat since 2 months. And my Dumerils boa lost only 50 grams although he did not eat since 3 months. So maybe they decided to stop eating in winter because they do not need food at the moment
