As it was explained to me by Dr. Kawasaki, a green stool means the food
moved quickly through the digestive system. It can be indicative of any
number of problems or just a non-problematic occurance. If all you get
is the one loose green stool I wouldn't worry. If it persists for a while
you should be concerned. After you've had ferrets for a while you can
sort of tell when you need to be concerned pretty easily. You also look
for other signs of illness like lethergy and changes in eating habits. A
change in foods is one of the causes of some looseness and greenness in
the stool also.
I imagine the good doctors around here might have something more to say
though.
