I have two females, one is 3'-11" long and weighs 705 grams; the other 3'-8" long weighs 655 grams. Two males, one is 4'-2" long and weighs 862 grams; the other 3'-11" long weighs 667 grams. I feed 2-3 adult mice every two weeks. Sometimes a particular snake won't eat a third mouse. Is this size and weight O.K. for adult corns that are active and in good health. I do not want to get them too fat but want to insure that I'm feeding them properly. Wouldn't it be desirable to have a table showing range of weights for a particular age and size (length) for m/f corn snakes? I know one can power feed but I mean for average growth. Thanks much for your replies. Don
