so it's been getting below freezing down here in Texas the past few nights and I noticed a draft near my snake rack I had a crack in my outside wall which I filled with insulation foam but the inside ambient temperature of my snake rack is still 5 10 degrees below normal with the cold spot at 70 I have to go to work tonight and will be pretty busy and don't have much money for the next two to three days. Will my snakes be ok sitting at 70 to 85 degrees for a temp gradiant for couple of days ? Thanks
