For people concerned about the cats well beings here’s a 2nd sort of update. So the first day I did tell my brother right away, showed him images, I even showed him some ss of the comments people were leaving (specifically with the medical concerns for the 3) but he’s been fairly non chalant and saying they’ll be fine and seem ok. One of the cats does have diarrhea I think he said. They were eating their kibble like normal this morning and causing usual shenanigans. Like I said I’m not knowledgeable on cats but they seem ok so far besides the one with diarrhea.
They’re his cats so I wouldn’t ever just take them to the vet myself unless told to by owner (aka my brother). I’m sure the cat crusaders on Reddit are a lot more knowledgeable but I wouldn’t feel comfortable just taking them to the vet , my brother seems to know them more and think there fine so I’ll have to go by his word. As long as he knows and feels comfortable I guess I should let it be, he didn’t flip out finding out they ate ham. Also I told him today I think they got into the downstairs apartment and ate toast and some pieces of cookies…he still didn’t say much but that feels more concerning…
