I think of it as, if the snake can strike, constrict and ingest the food, they will be able to know how to digest it. I always see problems concerning not eating, not constricting, not being able to figure out which way to eat the prey. I dont think iv ever herd of any problems with a snake not digesting its food properly. Unless it was handled right after feeding, or prey still being cold/frozen, which would most likely be a regurg. I used to worry about all the small things with my snakes. Im kinda new to all this but since being a part of this website, iv learned soo much, by no way am i saying im an expert or know it all. All snakes dont act the same way, eat the same or poo the same way. When i feed my boa, he sometimes takes 1 hr or more to start eating, my bp's take 5 mins. Then sometimes the boa will start eating right away.
