Even during nighttime, warm side temps should not go below 94-95, and cool side temps 80-84. Humidity can be around 50%, and no higher than 70% during shedding. If they are having problems shedding, you can add a humid hide made out of a gladware container(or other disposable plastic container), cut a hole in the side big enough for the snake to enter, place moist paper towels inside, put the lid back on and place the whole container on the warm side of the enclosure.

What are you using to measure temps? Also, what are you using for bedding? Different beddings hold heat and humidity differently.

Not feeding while she is on the antibiotics should be ok, but you can add some acidophilus(Snakes can have that, correct?) to help her build the gut flora back up. You can find it at any health store(GNC, etc). You may need to ask the vet for the dose. Just keep her warm, and her humidity low(45% is great), and only mess with her as need be.

With Sudan, I would place him in a rubbermaid container with a lid(small enough to fit inside the cage) and place about 1/2" of warm water in it, and leave him in there for about an hour. Just so he doesn't get cold, place the container, with him inside, on the warm side of his enclosure. He may just be dehydrated, or the eyecaps may be retained. After he soaks for an hour, let him run through a damp, rough towel, and see if that doesn't help get any of that off. If they don't come off, you can use mineral oil or even polysporin to lube his eyes up. NO baby oil, it is not meant to go on eyes.

Drop his humidity to about 70%, but try the humidity box for an hour. It should help. You dont want his enclosure wet for too long, or he could develop some scale rot, and that would just be another stressor to deal with.

Hope your guys get better, and update us on their progress. Welcome to the site, by the way!
