Hey Nitelion94,
The answer is NO and YES. My snakes poop is some times really runny most of the time it is normal soft. Just keep an eye on him and see if next time it is not normal looking. The meal you fed him may have had allot of water in it or something like that or he may have drunk allot of water.
Love the Fatman
P.S. sent me your Cornsnakes so you can get a Black Milksnake.
