Well, first, ferrets can get tummy upsets just like the rest of us. And at times, that does have to do with a change in their daily routine - so maybe the change in you not letting her out in the a.m. could have something to do with it. However, I would not let it go at that. I would schedule a vet appt Monday and get her in for an exam. (taking a fresh stool sample to the vet always helps too!). Meanwhile, if her symptoms or behavior show additional sighs of illness, call an emergency vet. She's eating and that's great - and playing too. Good signs always!
A bland diet of baby chicken food may help settle her stomach. I hope all turns out well - wish you the best of luck and let us know if we can do anything else!
