Vita-Mineral Mix
1 1/2 cups yeast powder (any food yeast: brewer's, torula, or nutritional)
1/4 cup kelp powder or 1/4 cup mixed trace mineral powder
1 cup lecithin granules
2 cups wheat bran
2 cups bone meal, calcium lactate, or calcium gluconate
Mix together and store in a covered container. Be sure to refrigerate.
Add 1 teaspoonful of Vita-Mineral Mix to each cat's meal (2 teaspoonfuls per cat per day).
Since veterinarians advise against supplementing commercial diets I'm not sure whether using this mix is a good or a bad idea.
In general she has some supplement suggestions that are not safe and are actually toxic and dangerous for cats, so I personally would not use anything she recommends without talking to my holistic vet first.
Earlier this year I actually did ask my holistic vet about one particular supplement and she advised against using it, especially in the amounts Anitra recommends in the book.
