I had a snow corn that died in August. It was fine, very active, and nothing was wrong. Then during one feeding he threw the pinkie up a few days later. I figured it might have been too big but thought nothing of it. A couple days later I was handling him and he was extremely limp, didn't even move around. So I knew something was up and I put him back. He died the next day.
Think the pinkie was kept on cedar, or some kinda spray used on it?
