We have tags for pooping and droppings. These seem to be the same bucket of questions; should there be a synonym here? If so in which direction? I'm not sure how I feel about "poop" as a tag name.
Additional thoughts: I think part of the problem, and why no consensus has emerged in the answers, is that we're trying to use both verbs (pooping) and nouns (droppings) here. If I have a question about why my pet is having trouble passing his solid wastes, I'm not going to think of "feces", "droppings", "waste", etc. On the other hand, if my question is about the output itself, I'm probably not going to be thinking of verbs like "pooping" or "eliminating". While any resolution of this should account for both cases (via synonyms), it might be worth thinking about which case we think will be more common and using that to choose the primary tag.
