When did he shed last? Many times I've seen snakes that aren't "obviously" in shed do this, only to find that a week later, they're in shed. So they obviously know it's coming way before we do, & don't want to eat.Another reason a snake might do this is if they're being over-fed. They instinctively grab the rodent so it won't hurt them (yes, even f/t), but still don't want to eat it. Or, maybe it's not warm enough to start with so he loses interest? (could it still be frozen inside?
)
