i could use some help with my sons albino corn snake. he is about 7 years old, we've had him for two years. last spring he didn't eat part of march, april and the beginning of may. i was told on the forum it was cause its breeding season and sometimes males will do that. he did that again this year but he is still not eating. he sits out all day curled up looking out of the cage. when i try to feed him he has no interest and will start shaking his tail at me. is this still normal for him to be doing?
