I have a corn snake about 12 weeks old. When I first got it the snake was very friendly and would let me handle him. A few weeks later one day I reached into his cage and he curled up in a striking postion and struck at my hand. After picking him up he continued to strike at my hand and bit me. Now everytime I put my hand in the cage to pick him up he coils up, rattles his tail and wants to bite! I don't know what to do or how to tame him. I thought by picking him up everyday even when he strikes over time would make him stop striking but he still continues to do so.
