Frequently Asked Questions

Does dry cat food cause kidney failure in cats?

There are only a few known causes for kidney disease. Genetic conditions such as polycystic kidney disease, toxins such as anti-freeze and lilies, infections and cancer are all known to cause kidney disease. However, nutrition plays an important role in managing kidney disease in cats. In short, the nutrition cat food contains is much more important than whether it’s wet or dry food.

Can baby food help cats with kidney disease?

Baby food should only be used as a treat, since it lacks taurine and other essential nutrients. A cat with kidney disease needs foods with protein restriction, additional potassium, lower sodium, low phosphorus and, in some cases, added Omega-3 fatty acids.

Can high protein food cause kidney disease?

High protein food is not shown to cause kidney disease but food high in phosphorus or increased levels of protein can increase the disease’s progression. The ideal diet for a cat with kidney disease should have a highly digestible, bio-appropriate protein content, such as pork, rabbit and poultry.

What food do I feed a cat with kidney disease?

Cats who are in the early stages of kidney disease do well on appropriate, commercial cat food. Wet cat foods are best because they contain more moisture than dry foods, but you still need to make sure the diet is made from high-quality ingredients. Cats with more advanced cases of kidney disease can benefit from eating a prescription food which are available ion wet and dry.

Conclusion

If a special kidney or renal diet is recommended for your cat it is important to find a food he enjoys eating. In addition to special foods, supplements, such as Omega-3 fatty acids, B-vitamins and antioxidants, can be added to help support for your cat’s kidney health.
