A-S was wrong about them being digested alive.
Birds’ respiratory systems are so sensitive that they would suffocate immediately (think 2 seconds) once the predator swallowed them. They wouldn’t even be able to process they’re being eaten.
Fluffies are anyone’s guess since they aren’t real and facts about them depend on headcanon.
You don’t need to do anything special. Just remember not to jump at people like that anymore, especially not on their own post.
