I’m guessing this question is referring to the classic “unaware pred” trope in macro/micro, which is commonly paired with foodplay as a method of causing the pred to accidentally eat someone. To answer the question itself… it depends.

I don’t dislike the scenario, especially since macro/micro + foodplay + stuffing is a fun combination, but it has to be pulled off really well for me to enjoy the unaware pred aspect. You lose some of the dynamic between the pred and prey when there is a disconnect in their understanding of the situation (which is the whole point, I’m aware. It’s supposed to be a cruel and frightening scenario. That’s the whole appeal).

But it has some good potential with the right pred. A character who would never ever eat someone accidentally swallowing someone without even knowing… you can make some really sweet and nice characters do something incredibly cruel on total accident. Then, you can have the pred realize what they did quickly after (by becoming aware of the movement in their stomach, or somehow hearing the prey’s voice only after they’re swallowed), and have them scramble in a flustered panic trying to figure out how to save the prey. Or… you can keep it unaware for the duration of the digestion. Maybe the pred only finds out what they did after burping up something identifiable as the prey’s clothes/belongings… and they have to deal with the terrifying realization of what they’ve accidentally put someone through.

… but that’s sad! And interesting… but sad. Imagine that same pred getting the prey out and having a comically silly interaction after that weird experience. Ya’know, to wash the sour taste out of your mouth.

Sometimes I’ll read some stuff with this trope, and the pred’s reaction (after finding out someone’s in their belly) almost always ends up being “ah… I ate someone? Ok, whatever”, which I think is supposed to be your typical cruel/gluttonous pred behavior… but it feels kinda boring.

But the TL;DR of this is that I only really enjoy the trope half the time. I usually prefer lots of teasing from the pred in foodplay scenarios, alongside intentionally stuffing themselves with food to mess with the prey after eating them. Obviously that takes an aware pred.
