If you consider your snakes your children, then why don't you do what it takes to give them proper care.
Look if my kids needed heat, i'd give'em heat.... I'd crank the heat up in that room so fast it'id make my fiancee's head melt...... Tell her to go sleep on the couch until the kids get well.....and if you have to, sleep with a fan pointed directely on you.....
time to man up here....GET SOME HEAT FOR YOUR CHILDREN ! ! ! !
Look you got some snakes with bubbles comming out of their mouths and are popping and wheesing when they breath, another with scale rot, sounds like you have some serious husbandry issues.
How does someone who has kept snakes as long as you have, allow them to get in such a sad state of affairs.....
Don't mean to be harsh here but, I wouldn't want to be your kids.....
Many here like myself have kept snakes for well over a decade.... and I have never had a snake get sick in anyway shape or form knock on wood...and I will say, I don't consider any of my snakes as my children....but if one of my snakes should show any sign of illness I would get them to the doc........
