Funny you should mention that. I was at a show this past wekend and visited with a close friend, Rick Krumrine. When I got there, I noticed a few snakes had pooed. I asked Rick when he fed them, and he said he fed them a day late (Wed.). Between feeding late, bringing them out into the cold, then rewarming them at the show, these little guys (some not so small) were poo factories.
I personally have never had one of my snakes pee or poo on a customer, but I didn't sell at shows, so we didn't have too many chances for this to happen.
I'm sure Mr. Murphy is a visitor to most herp shows, so I'm sure it happens all the time.
