My nutrition veterinarian Dr. Lisa Weeth DVM DACVN recommended to stay away from cat food that had Tricalcium phosphate or Dicalcium phosphate in it. I did an internet search to find out why and found this article summarizing much of the research done.
Calcium phosphate,Tricalcium phosphate, Dicalcium phosphate and even Sodium phosphates, etc all contribute to kidney failure because of how much more phosphates get taken up into a cat’s blood compared to a natural source of phosphorus. I think you should read this article and pass it on to your nutritionists formulating your cat and dog food and change your source of phosphorus to something safer and perhaps more natural. It is not just how much phosphorus is in a can of cat food but also how much will end up taken up into the blood affecting the kidneys and contributing to kidney failure.
