People have posted some pretty unattractive things on youtube, which are perfectly legal. F'r instance snake feeding times, the thing is the posters usually know they're gonna reap some upset messages and respond "Hey, it's just nature taking place when I leave my bunnies in the same room as my constricter."
The posters get off on the outrage.

Slamming around the cat in my opinion he got what he deserved. But if he'd fed it to the constrictor he'd've been covered.
