Bunny owner here, I can answer this!
Rabbits produce two kinds of feces: normal “waste” feces and edible “cecotropes” or “cecal pellets”. They generally eat the cecotropes immediately after excreting them, and only drop the waste into their litterboxes.
Amazing game, one of my all-time faves.
If you’re not into hiding/running from monsters, there’s an option to turn enemy aggression off so you can just play through the story, which is the real gem.
