Yup...almost always happens once the snakes are mature. My two little girls have been slamming food consistently all season, but my male pastel (who is now mature) had been off food since Jan 6th. until last Wednesday. Hopefully he'll eat again tomorrow, but I'm not holding my breath.

My corn snakes have been doing the same thing - the boys haven't been interested at all in food whereas before they slammed mice like they were going out of style! Heck, my male Amel had the same record as my male pastel for not eating.

Bottom line - don't worry. Keep track of their weight and overall condition, and unless they're loosing a lot of weight fast, just sit back and wait for them to let you know when they're ready again.
