Don't sweat it. Snakes don't eat because of boredom, they eat when they're hungry. Try feeding it every 2 weeks until it eats. It will eat. At some point it will eat. Maybe not when you want it to eat, but it will eat when it wants. I've got a male albino that drives me crazy. He eats a LOT less than any other snake. I've learned to feed him earlier than the rest. If he doesn't eat, the rat goes to another snake. He eats when he wants, not when I want him to eat. He stops eating for a week to a month, then he eats, then he stops again, etc.

Don't sweat it!
