I've heard that depending on your location, if someone decides that the people recording were getting 'amusement' out of it, live feed videos can be construed as animal cruelty. I don't know how accurate that is, but I figure it's better to be over-cautious considering most people that don't own snakes are going to sympathize with the mouse.

If what the snake swallows seems smaller than what they generally poo, there's really no reason to worry. Bedding like that can be bad news for smaller types of snake (like garters) but is fine for a BP.
