I know of a company in the United States that sells frozen meats & poultry. The also sell frozen meats mixed with vegetables. They specialize in natural (raw) dog & cat diets, and sell vitamins & mineral supplements. All the meats, poultry, & vitamins & supplements come from the finest natural sources. For example, they used New Zealand beef since in New Zealand the cattle are not given antibiotic or growth hormones. I know the owner of the company raises show cats & kittens. She has had cats that have lived to be 28 years old (maybe older.) I have no degree in ferret nutrition, but if you want the company's web addy. Just let me know in a private e-mail. Brian.
