I feed everyone a mix of mostly Totally Ferret with a little of each of several other good ferret foods. Even Marshall's, a little. That is sometimes full of small crumbs and powder so I sift it out with a colander. I do that with the crumbs and bits in the bottom of the bowls, and I put it out for the birds. But when I put out the Marshall's crumbs the birds wouldn't touch that. Maybe because it wasn't in pieces but in powder, but I think because of its base of fish. I think the birds are telling me something. Also what is the opinion of the new formula 45% protein 8in1 Ultimate? I got in a bag with a couple ferrets and it was their only food. They are in good condition but lean. It has only 16% fat. So I am going to use the rest of the bagful in the mix. Carol Owens, Ferret Friends, Tucson [Posted in FML issue 5174]
