Why is my ferret's poop green and runny after a diet change?

I just rescued 2 more ferrets well they were on cat chow indoor. I did not like that at all. So I switched them to the food I feed my ferrets and now my 2 year old male is pooping runny almost leaf colored green

If this is from your ferret that was there before these two came it may be due to stress from the new arrivals. As long as he's eating, drinking and acting normally I would give him a day or two to see if this resolves. Also checking a fecal sample for parasites is recommended. If the diarrhea worsens or he seems lethargic or sick please take him in for an exam and treatment. They will make sure he's not dehydrated and give him medication to control the diarrhea.
