i dont know about anyone else but that set-up sounds a little ridiculous from what i have read about it . . . if you have a BP and know how to properly care for it (temps, humidity, tank size, feeding) maybe you should go over it with ur friend and get that snake into a proper set-up/enclosure when he gets back from the vet . . . you said you know about BP's but not about illness so sit ur friend down and go over everything you know with him to avoid this in the future, isn't that what friends are for?
