Corn Snake Not Eating

There are a couple reasons for a corn snake to not eat. But here I will list the three most likely to be happening listed in order. 

Shedding

One of them being he/she might be shedding, when a corn snake is shedding he/she will not eat or if he/she does there is a possibility he will regurgitate the food. Also while he is shedding if he does eat the food it may make him sick because he is working so hard to get off the execs skin, and may not digest it correctly. 

Breeding

Another reason that he may not be eating is that it is breeding time. During breeding corn snakes will eat as much as they can and then should not eat again till spring. So even if you don't breed your snakes instinctively they may not eat. 

Not Hungry

The last and most obvious is that your corn snake may not be hungry. Rare in Corn snakes but totally possible. Most of the times if this is the reason its because he probably didn't finish digesting his last meal.
