Can you afford to take this snake to the vet if it ends up in poor health? Do you have a proper setup, supplies and ability to QT this snake away from any of yours for several months? It's not a rescue if you can't put it in a better situation which is a mistake I see many on here making. Personally I wouldn't touch it with a 10 foot pole because it's not worth the risk to my collection of spreading disease/bugs or the hassle of paying someone almost normal price for an unhealthy poorly kept animal, probably spending a good amount of time and money getting it back to health (if possible) when I could simply buy from a good breeder and get exactly what I want.
