Sean Marrinan: A couple of drops per day of Ferretone is all that's needed. Too much will cause the fur to become dry and brittle - it will also cause stool to be soft and mushy. Marshall Farms Food is an excellent food - however, I don't ever feed my ferrets just one food. Blend in other foods as well - Totally Ferret, Iams Kitten. This allows them to be more open to new foods. Ferrets tend to fix on whatever food they are eating as a kit, and that becomes the preferred food for life. In later years, if you need to switch a diet for health reasons, you will have one heck of a time if they've only been eating one particular brand. Clumping Litter: A recent report from a cat breeder in CA indicates this may not be the best litter to use. She lost several litters before she realized the kittens were ingesting the clumping litter when cleaning themselves. It collected in their stomach/intestines where is caused blockage problems, dehydration from drawing off stomach and intestinal fluids into the litter, and other problems. Once she switched back to a regular litter, her survival rate went back to normal. Debbie Riccio WNYFLFA Rochester, NY [Posted in FML issue 1240]
