Well fsty their diet isn't really a completely raw diet. They still have kibble at all times in there cage but I also give them a whole mouse twice a week and on other days they get either chicken, turkey, or rabbit (sometime raw, sometimes cooked). Some people actualy recomend giving ferrets live mice because "hunting" stimulates their minds. I just find that a little cruel for the mouse not to mention really gros to hear. Instead I hide pieces of meat in their cage for them to find. I also give my ferrets a good supplement every day like linatone.
Feeding a raw diet to ferrets doesn't change their temprement at all. That's a big myth. As far as who eats what well, Tweak is the fussy one he'll only eat chicken and rabbit but mostly kibble. Jynx will eat any meat but she prefers mice. Dude well he'll eat anything that isn't nailed to the floor.
I smile because I have absolutely no idea what's going on!
