Heating is turned off

glacey,
there's your problem right there,I can only assume your not supplying any heat at all?If this is the case them I'm surprised the rest of your snakes aren't sick as well.15-20 degrees maximum is way too cold for carpets,they still need to be able to bask and warm themselves even in winter.25 degrees is plenty cool enough for a day time minimum in winter,any lower and the snakes immune system can't function properely.All my childrens,olives,blackheads and womas are all still at 30 degrees during the day,even though they are being cycled for breeding.They get 6 hours at this temp then the rest of the time the temps gradually drop to about 18 degrees during the night.Carpets I run at about 27-28 degrees during winter cooling with night temps only getting down to about 17-18.
At this stage I 'd warm up the snake in question look out for any signs of illness.I certainly wouldn't go worming it at this stage,if your snake is infact sick worming could do more harm than good.
