Has anyone ever been pooed on by their snake? This has happened to me twice now. Once with my corn snake, and once by the BP.

This BP hasn't eaten since November, and we had her out for the evening a few weeks ago. After a few hours of just chilling, she took a runny crap. Went all over the floor! Is this a sign of stress or something? Or do they just go when they feel the need to go?
