My girlfriend and I have had a adult female ball python for a few months and every time she sheds it's always in pieces. She has a water bowl big enough to soak in and we mist her substrate (ReptiBark) when she is in shed to add extra humidity. We don't have a hydrometer in her tank because we were under the impression that ball pythons aren't terribly sensitive to humidity and don't need it above 50%; she's in a small room with lots of aquatic setups so the ambient humidity in the room is already pretty high. However every time she's in blue we find shreds of her shed spread around the cage for the next day or two.

I'm assuming we can't soak her while she's in shed because that would stress her out so much and/or we might get bit because she's freaked out. Is it just a matter of getting a hydrometer and monitoring her humidity more carefully when she's in shed? Is regular misting of the substrate the best way to get her the humidity she needs?

Thanks!
