I am relatively new to the FML and I enjoy it very much.  Perhaps the
answer to this is in the FAQ so please direct me if I've missed it:
How do you feed a 4+ and a 1- year old ferret living in the same
area, eating from the same container.  I understand one (the younger)
needs a higher protein content in the food than the other.
