I see the Geriatrx has Chicken giblets as an ingredient and they told me any organ meat is a purine. Is that true?
All foods contain purines as part of their nucleic acid content. Organs are higher in purines than muscle meats, however, please keep in mind that chicken giblets contain a large portion of gizzard, a muscle. Also, organs are not the only ingredient or even the first ingredient in Geriatrx. Remember that the dosage makes the poison. When feeding a variety of foods, specific amounts of food componenets is inconsequential.
