In 2009 I found a hit timber rattler on the road, it was still wiggling around, so I picked it up careful and threw it in the truck. I took it to a buddies and showed him and his wife, it was dead by the time I got there. Got it home and skinned and as I was looking at the skinned thing I thought, "Wow, there's a lot of meat on there". I fillet the meat off the bone, between contusions, and we fried it up for dinner. My neighbor came over and asked if I'd cut into it's belly to see if it had anything in there. We cut into it and it had a half of chipmunk in there that smelled like $#!^, we were all gagging. Anyway, we looked for the heart and to our amazement...yep you guessed it, it was still beating. I had snake in the belly of my family and the heart was still beating. Pretty freaky.
