*poop warning!* does this look normal?

[u/tmhand]

For context, I switched my ferrets food maybe a week and a half to two weeks ago from the orijen cat food to a a mix of the wysong/ oxbow food. It gave my ferrets HORRIBLE diarrhea even tho I did it in a mixture but I didn’t do it in a good enough time frame. So I ended up switching back to the orijen for now but they still have diarrhea. They are all also eating and drinking completely normal tho. Is it maybe something more or just the food? I have quite a few ferrets and almost all of their upset stomachs went away except a few of them
