I have heard so much regarding the proper size prey to feed to corn snakes that I decided to do an experiment. If you follow the Munson feeding plan you have a pretty good idea of the gram size prey to feed corn snakes, depending upon their weight in grams. For my experiment I took 8 corn snakes between the weight of 42-47 grams that were usually fed 9 gram fuzzies. I fed each of them weanlings last week that weighed 17-18 grams. Way larger than I would typically feed. All the corns ate the oversize mice with no problem, and the large bulge in their stomachs was obvious. Much to my surprise none of the corns regurgitated their weanling. While I'm not suggesting that you should jump up that far in size, it goes to show that perhaps we keep young corns on small prey items too long.
