I have. He is a trustworthy guy. When I sent him a message, he wrote back saying that sometimes snakes just don't want to eat and it might be a change in environment. I have another snake from him that eats like a champ. The only time he misses a meal is when he's in shed.
One observation though. When I went to offer food to the snakes yesterday, the bigger female, Akina, was in shed. Milky eyes and dull coloration, even though she hasn't eaten in 3 months. Is it normal for a snake to shed even when they are not eating?
