If you’ve followed us for a while, you already know that we’re big fans of Darwin’s raw food. It’s Allegra’s favorite, and we like everything about this food. Today, I’d like to introduce you to a unique offering in the raw food market: Darwin’s Intelligent Design™, a raw diet for cats with kidney disease.

The right diet for cats with kidney disease

There is a lot of controversy and misinformation about feeding cats with kidney disease. Conventional vets tend to recommend a prescription diet for cats who show even a slight deviation of normal kidney values. That’s because there are some research trials – not coincidentally, sponsored by the very companies that sell these diets – that have shown that restricted protein diets can prolong renal function.

However, feeding a cat with kidney disease is not as simple as restricting protein. In fact, restricting protein for an obligate carnivore may do more harm than good. Since protein restriction impacts healthy body condition, a good diet for these cats should contain high quality protein. When protein is inadequate, cats start to loose muscle mass.

There is no single diet that is right for all cats with kidney disease

Multiple factors are important when it comes to diet for cats with kidney disease. An appropriate diet for these cats should contain additional potassium, reduced sodium and phosphorus levels, and increased omega-3 fatty acid levels. The most critical element for a diet for cats with kidney disease is moisture, which makes dry food the worst possible choice for these cats.


Darwin’s Intelligent Design™ Kidney Support Formula

Darwin’s offers a specialized formula designed to provide extra support to cats facing kidney disease. These highly palatable and nutritious meals use only hormone-free, antibiotic-free, and pesticide-free meats, with no grains, added fillers or chemical preservatives. Key benefits of this diet include

  • Appropriate protein levels
  • Restricted Phosphorus
  • Included natural Phosphorus binder Chitosan
  • Increased calcium levels (minimize P absorption)
  • Enhanced long chain Omega 3 Fatty Acids for glomerular health
  • Increased Vitamin B levels to replace those lost in the urine

Darwin’s Intelligent Design™ Kidney Support Formula requires a prescription from your veterinarian.

3 Comments on Darwin’s Intelligent Design™ Kidney Support Formula

  1. I have purchased Darwin’s raw food in the past and my cats ate it for a year and then decided no more so I switched to high quality canned food. Recently my 16 yr old female cat was diagnosed with kidney disease, 3rd stage and my vet prescribed the Darwin raw kidney food and she will not eat it. I have tried several times even mixing with her other food. So now I have a freezer full of this food and my cat isn’t getting the right kidney diet. Very frustrating, any suggestions?
