Hi,
What is your ferret eating as his main diet? It is possible that there are
artificial colors in his food that make his poop different colors. This is
not a problem and will not harm your ferret in any way. I used to feed my
ferrets Meow Mix and they had orange and yellow poop also.
Good Luck!!!
