It's normal to see some blood after a shed. It doesn't happen all the time or with all snakes, but it's not uncommon at all. The tissues around the vent are delicate and can sometimes get torn a little if the snake is an "enthusiastic shedder." So long as the bleeding does not continue beyond a few minutes after the shed, everything should be fine.


Of course, a vet check is always wise if you're concerned about something. You know your snake and nothing can be or should be diagnosed over the Internet.
