We are big fans of Darwin’s raw food. it’s currently one of Allegra and Ruby’s favorite foods. You can read our review of Darwin’s here. Today, I’d like to introduce you to a unique offering in the raw food market: Darwin’s Intelligent Design™, a prescription diet for cats with kidney disease.

The right diet for cats with kidney disease

There’s so much misinformation out there about what cats with kidney disease should eat. Many conventional vets will recommend a prescription diet such as Hill’s k/d for cats who show even a slight deviation of normal kidney values. That’s because there are research trials – may of them sponsored by the very companies that sell these diets – that have shown that restricted protein diets can prolong renal function. However, there is much more to feeding a cat with compromised kidney function than simply restricting protein. In fact, protein restriction may not be indicated until the very final stages of the disease. Until then, the consequences of making poor dietary choices in these cats can be dire.

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. Moisture is critical. A good diet for these cats should contain additional potassium, reduced sodium and phosphorus levels, and increased omega-3 fatty acid levels. 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. Feline veterinarian Elizabeth Colleran explains in detail what cats with kidney disease should be eating, and it may not be what your vet is telling you.

4 Comments on Darwin’s Offers Raw Prescription Diet for Cats

  1. Is this food really helpful? My cat has kidney problems and I don’t know witch food to choose for her. Please help me if you can Thank you.

  2. My holistic vet prescribed this for my senior ckd girl. There are no samples, you have to purchase in 10lb increments so you’re spending over $70 to try it (I forgot the total, sorry). Tessie didn’t care for it so it languished in my freezer for several months. When she stopped eating most of her favorites, i dug out tge Darwin & fed her small amounts from my finger. Not ideal, but i knew i was getting good stuff into her. She growled when i did it for too long so I’d stop. I don’t do it all the time, but when her weight drops or I know she’s not eating enough, I supplement her diet with it. I wish she’d eat it voluntarily! Day after she eats it she seems to be more active 🙂

  3. I was so excited when I heard that Darwin’s would offer a diet for kidney cats.I suspect many vets will not give the prescriptions needed. Most vets talk about raw diets as akin to poisoning your cat. I have a good friend whose cat has kidney disease, I try to share info with her but, her vet wants that cat on kibble ” to maintain weight” ugh. Hard for me to believe that enough vets will write a prescription for Darwin’s. I hope I am wrong.
