regarding blood pythons: im lucky the one i picked out from a dozen individuals is very handleable/docile. the ones i was selecting from were very unpredictable and bitey. the one i got was the smallest in terms of girth but it's fine. i will just fatten her up in no time (she just ate a med sized mouse today ). regarding their poop issue, i think it is part of blood python keeping, we just have to deal with it.
