Wow, lots of "he's stressed", "he's exploring his new environment".

He may be hungry and out hunting. If you're concerned, try feeding. I've fed every new snake within a day after I've gotten them, they've all eaten. Getting a refusal will not imprint your snake for life.

My philosophy is to give the snake what he wants. It took me 5 months to figure out one of my snakes and that is to toss in a live mouse, go away and let him eat in peace. My others, 3 take f/t off tongs, and one I have to leave the f/t prey in his cage, go away and let him eat in peace.

What these other people are saying is it may cause problems if you feed too soon. Not that it will.
