Two weeks ago I too had a stomach virus. Because I was having surgery I went to the doctor for medicine. When I came home from my surgery my children surprised me with a new ferret Lilly. the next day Oscar my 1 year old male started pooping green. I was so upset I loaded Oscar and Lilly in my car and went to the vet. (6 days post op hysterectomy!) My vet told me Oscar had Rota virus. She started him on Chloramphnicol 250 mg, and pedialyte. It has been three days now and his stool is still loose but no longer green. My vet said this could last a week and it is a virus that is passed either from human or ferret. Hope this helps.
