mg phosphorus per 100 kcal — for comparing foods, not a recommendation

This food provides 100 mg of phosphorus per 100 kcal. Many cats with CKD benefit from a veterinarian-recommended renal diet or an individual phosphorus-control plan, but a food’s phosphorus number alone doesn’t decide whether it’s right for your cat. Ask your vet, based on lab results, appetite, calorie intake, body condition and other health conditions.

Prescription diet

Prescription diet — follow your vet’s guidance. Renal diets are adjusted in several ways besides phosphorus, and studies link them to longer, better lives for many cats with CKD.

How we calculate

US labels list nutrients as fed, including all the water. To compare foods fairly we convert them two ways:

Dry matter basis (DMB) = as-fed % ÷ (100 − moisture %) × 100. This removes water, so a pâté and a kibble can be compared.
mg per 100 kcal = as-fed % × 1,000,000 ÷ kcal per kg. Cats eat to meet their calorie needs, so this shows how much phosphorus comes with the energy they eat. We highlight this number.

When a food has no calorie statement we estimate calories with modified Atwater factors (3.5 kcal/g protein, 8.5 kcal/g fat, 3.5 kcal/g carbohydrate) and say so on the page. Estimates can be off by 10% or more.

We don’t label foods “low”, “moderate” or “high” in phosphorus: there is no accepted veterinary scale that says which number is right for an individual cat with CKD. We show the number, its source and how it was calculated, so you can compare foods and talk it through with your vet. A food’s phosphorus number alone doesn’t decide whether it’s right for your cat.

Nutrition figures are for information only and come from the source shown. Formulas change, so check the current label. Many cats refuse renal diets; some vets suggest lower-phosphorus regular foods as an alternative. Always discuss diet changes with your vet, and never stop a prescription diet without their guidance.
