How long does it take for a corn snake to digest a mouse?

could it take 24 hrs ??? --- not sureyou should wait to feed your cornsnake again until you see that it has pooped, that usually means that within 24 to 48 hrs it will be hungry again, or at least that's how mine is :)~, or you could try offering a live mouse once a week, if he does not take the mouse within an hour, take it out and house it or take it back to the pet store, and try again a day later, cause the mouse will get up courage and attack your snake. if your snake is eating frozen mice, i would get him on the once a week schedual, or just wait for nature to come calling and watch for poo.
