I always assume the snake hasn't eaten when I get it shipped in, unless I'm told otherwise. I do try to see when the last time a snake ate when I buy it. But you know how big breeders can be.( Doug aka sho220 told me the exact date) The one snake I picked up at a show actually didn't eat day one and come to think of it, its the only on that didn't eat day one for me. I imagine being on display might have had something to do with it, or maybe he just got a meal........guess I'll never know.
