Cats need an optimum protein intake to keep them healthy and active according to their nutritional needs in well-balanced diets. As carnivores, cats require protein, and seeking low-protein diets is a health practice aimed at advanced kidney care rather than a preference.

As a pet parent, striking the balance of protein and other essential nutrients in your cat’s diet is best assessed by your vet. Excess protein feeding in cats leads to regular urination and water intake leading to kidney diseases. On the other hand, underfeeding protein to your cat leads to a weak cat due to weight loss.

If your cat is diagnosed with liver or kidney complications, low-protein diets are recommended by vets. Key suggestions include low-protein diets that are highly digestible according to the ingredients used. In consultation with your vet on planning the best diet, picking your low-protein cat food choice can be challenging considering the varieties available for cats with kidney disease.

We have compiled a list of the best low-protein cat foods available today as a guide to setting up a healthy diet plan for pet parents.
