QUESTION:
I have 2 ferrets, one which was just introduced to the household 4 days ago. The new one is a 9 week old female. Our older ferret is 1 year, and he has the "greenies" for the past day. He is still drinking and eating. I haven't noticed any vomiting. My question is, is this ECE, or can they get green diarrhea from other things, such as a new treat, or an out-dated treat? The younger ferret is showing no signs, she is eating and drinking fine.

ANSWER:
ECE shows up as very liquid green diarrhea that shoots out. I would doubt very seriously that your 1 year old has it, as he most likely would have already been exposed to it previously, however if you are seeing the diarrhea as I described the it could be so. You will need to watch to make sure he is eating and drinking plenty, as he will dehydrate. If he isn't eating well then you might want to get him some CHICKEN BABY FOOD and feed him that, it is high meat protein and easily assimilated, plus it is very bland (it makes a very healthy snack for your ferrets). The other reason your ferret may have the green poops is STRESS from introducing a new ferret and after he gets used to the newcomer he should adjust. Young ferrets can also come from the Pet store with parasites or bacteria and show no signs of sickness themselves, but can/will give it to other ferrets. If the problem continues then you will need to see your vet for a stool check to make sure your ferrets do not need medication.
