Mixed menu of the day

Is it okay to feed ferrets the heart, liver and kidneys from rabbits on a regular basis, or is the offal too rich for their systems?

Edward says:

It is bad to feed any species the same stuff daily – just see how long you’d last on nothing but chips and baked beans! As ever, the best diet is a mixed one. My ferrets get fed whole rabbits, chicks, game, fish, or anything that I can get my grubby paws on.
