I've recently aqcuired an adult Northern from a pet shop who eats well and seems healthy, but boy-howdy does his poop stink! It's somewhat watery and not well-formed like my leopard gecko or uro, either. I'm hoping other keepers can tell me if this is normal or cause for concern. The pet shop acquired him from a local private zoo, although I don't know much else about his history. I've got a few 250 MG tablets of Flagyl I could treat him with, but could use some advice on dosing amount and method of administration.
