Should i get this corn snake? is it normal that it eats two times per week?

a GOOD rule of thumb when you get a snake is to feed when he poops. This will give you a good idea of how much poop there is and how much to feed him. Two to three times the size of the poop should be about right, and you can go from there. If he will eat more, offer him more. Because of the size of the snake size, some people would rather feed smaller mice more frequently (twice a week instead of once a week). I had a very large constrictor that ate very large food. He only ate once every two weeks. When I couldnt get the large bunnies (dead), he ate ex-large rats, but ate about every four days. When he didnt eat, we just refroze and waited a couple of days. He always let us know when he was hungry.
