There's so many stomach bugs that have the same symptoms so it's hard to distinguish just by looking up the symptoms/onset timeline.

Like every single one is "nausea, vomiting, diarrhea, fever/chills, aches" The cat piece (since they can't catch most human stomach diseases) plus I know this isn't rota/noro is really the only thing that's making me think Salmonella vs like ecoli clostridium perfringens, listeria etc etc

It's just weird, never had something like this before and the fact that two people that I haven't seen in longer time than the incubation period (so likely got this independently) also makes me think that maybe it's from an minor outbreak in the area

Just all guesses at this point
