The sick snake was on RepitBark, and is now on paper towels, the ReptiBark was almost brand new when she got sick, and was clean. The pet store was using HotShot to treat for mites, on a snake that I once owned (6 1/2 foot Red Tail Boa), but was not near the feeders. I checked temperatures with an analog thermo/hydro combo, 3 times daily. They had just gotten in 2 cb BP babies, one of which was just extremely tempermental, but the health of the Burm, and all the BPs are excellent as of now, I just ot off the phone with him. Also, how much would a necropsy generally cost? I figure that I would have to send her body off for it. All snakes are quarantined atm, and everything is disinfected with a 10:1 water/bleach solution. No one, literally no one, around here has ever had a problem with IBD, ever. So none of us here really know much about it, except for what I have read on the internet about it. Thanks guys, I appreciate it.
