My 8 year old son has a 6th month old corn snake. A few months ago the screen on his cage got stepped on. My husband fixed it with duct tape. Unfortunately, Popcorn (the corn snake) got caught in it. We thought she was going to die. My son was so upset. Someone suggested we take the snake to a vet. We did, and they got her off using mineral oil. If this ever happens to you try mineral oil or olive oil and a Q-tip to prevent tearing the skin.
