A Cat Food Guide For Kidney Disease

Tuesday, August 13, 2019
posted by Jim Murphy

If your cat is diagnosed with Kidney disease, a change of diet is usually required. That can be a daunting task since cats can be very fussy eaters. Low phosphorus is key in foods for Kidney disease. Unfortunately, many brands don’t list phosphorus levels. Royal Canaan and Hills are a couple of the main brands that vets prescribe for cats with kidney disease. The problem is many cats don’t like this food. Are there any alternatives? I fed my cat Weruva which does contain lower phosphorus levels.

I always used Tanya’s Comprehensive guide. It’s very detailed and contains lots of information about Feline Kidney disease. Indicated below is an excerpt listing various cat foods and nutritional information.

 

  1. Hi-Tor Neo
  2. Dave’s Pet Food Restricted Diet Protein Phosphorus This food contains alfalfa, presumably because it is thought that alfalfa may support the kidneys. However, alfalfa contains a natural anticoagulant which may increase the risk of bleeding. The Veterinary Support Personnel Network states that alfalfa is toxic to cats. This food also contains parsley and dandelion, which are diuretics and thus not recommended for CKD cats. It is also not clear if this food has increased amounts of essential fatty acids, which are recommended for CKD cats.
  3. Forza10 Renal Active Contains some questionable ingredients such as dandelion (diuretic) and cranberries, neither of which is recommended for CKD cats.

Here are lists of the composition of the various diets available on a dry matter analysis basis (the calories are as fed):
