I have an adult corn snake.
He has always been a good eater. He has never regurgitated, and only once refused food.
Tonight he ate a medium rat. He's fat so the rat didn't make a dent. After eating he came back to the bowl looking for more, and if I approach the cage, he comes out looking at me to feed him.

Could he possibly want two medium rats? It seems like more than the care sheets call for.

He might just have a very healthy feeding reflex. My boys aren't great eaters, but once they do eat they stay in that mode for quite some time, and get pretty perky faced if they think they might get something else. It's possible to overfeed snakes that are like that. Your boy is fat and healthy, I'm quite sure he's just being interested and greedy rather than actually hungry.
