I've never seen this before, and didn't know snakes could/would do this. We keep 5 red corn snakes in 3 different tanks, and run a small mouse ranch to keep them all fed. Every Sat or Sun is the snakes' dinner day. Yesterday I had put 2 mice in the first tank for the 2 snakes inside. They each quickly grabbed their own mouse & coiled up around it. We moved on to feed the other 3 snakes. When I looked back into the first tank, the 2 snakes were having a tug-o-war with one mouse, leaving the other on the floor. Since our local PBS TV station has gone all digital, leaving us without our weekly Nature program to watch, I called the boys over & we settled in to see the show in the snake tank. The 2 snakes were pulling on the mouse & winding themselves around each other for several minutes. Then one of them, Tattoo, finally grabs it and moves to a corner to swallow it. That's when I notice the other snake, Snakey, is mid-way through a shed. Snakey is about 3 feet long and takes a while to completely shed. While I'm watching Tattoo swallow and Snakey shed, Snakey sees the other mouse on the floor of the tank. And begins to swallow it! At the same time as shedding! It was so interesting to watch. The 2 snakes ended up with their heads almost side-by-side slurping down their mice in tandem. But Snakey is also doing a sort of serpentine cha-cha half-way down, so the skin can continue to detatch and the tail come out. Although it shouldn't come as a surprise that Snakey can multi-task. Because Snakey is a female snake!
