So we have a Stimson's python who for the past 6 weeks has shown no interest in its food? the heat mat is at a good temp but maybe the outside temp is too cold?? we have asked at the local pet shop and the guy in there said snake s can go up2 6 mth without food but our concern is we go away in few weeks for 6 weeks do we just leave him, he will be fine? or what do you guys recommend? bigger heat pad under the enclosure or ceramic bulb for heat or just leave him till weather warms up??Any help please
