First of all, Welcome to our site! We're glad to have ya around .

Its quite normal for a snake to go a while without pooping. From my experience it takes anywhere from between 4-6 feedings before i see any poop, however every bp is different. If you are concerned about constipation, you might try to soak him in some tepid water. Remember tho, if the water seems warm to you it will be too hot for him.
