All three of my craigslist rescues were in bad shape. My first was a little hatchling who was dehydrated and starved, my second was a 4 year old who was also dehydrated and starved, but was also covered in scars and had a blood infection that went septic (currently treating, she's getting much better). And finally, the one I got last night is about 4 feet, as big around as my yearling female, weighs the same as her, has burns on his belly and sores on noes/chin from rubbing. I'm working on getting it up to par, hopefully it won't require vet treatment (not exactly rich at the moment). It also has red flecks on the chin and a spot on the neck. They look like blood spatter, and the snake was fed live, but the blood would have smeared. There are no mites that I can see, so if anyone has any idea what they could be, please PM me. (It's no the beginnings of scale-rot, as the flecks aren't blister-like.)

Anyway, if you're picking an animal up from craigslist, do NOT agree to make a final purchase until you've seen the animal yourself in person, and give it a thorough examination. If it's not healthy, PLEASE don't be afraid to speak up.
