I could be completely random, or it could be because of the winter...
My guys are eating champs....never turn down a meal.....
BUT
I have read that if snakes can tell that the seasons are changing, or sometimes even if they can't, they will still try to semi-hibernate(brumate? i think hibernate is for mammals...its early and my head hurts)
anyway....and either one, that does include less activity and sometimes not wanting to eat.....
as long as everything else seems on the up and up then it should be fine until it doesn't eat for like a month or so.just keep trying every week or so, and let us know when it eats......
