In Depth: Should I Feed My Cat With Chronic Kidney Disease A Raw Diet

The internet is awash with recommendations, forthright opinions, and recipes for cats with chronic kidney disease . This is concerning it’s one thing for people to give bad nutritional advice for a healthy adult animal, but it’s another thing when it’s for an animal with a medical condition. Poor nutritional management of cats with CKD will shorten remaining lifespan and increase secondary complications – that has been well-established in cats, dogs, humans and many other species.

So in this post, I thought we would have a look at some common nutrition-related questions for cats with CKD, and also analyse an easily available free recipe and see what it looks like. This is a longer post, but if you are interested in feline nutrition, please do persist.

I’m going to get stuck into the hardest and most controversial question first, which is:

Should a cat with kidney disease be fed a protein-restricted diet?

This question has previously been a topic of contention and debate, even amongst board-certified veterinary nutritionists.

What Can I Feed My Cat With Early Kidney Disease

If your cat has recently been diagnosed with kidney disease in its early stages, your vet is the right person to make the best recommendation regarding your cats condition. Canned over-the-counter kidney care cat foods can be good options, as canned wet food contain large amounts of water compared to other dry food alternatives.

At the same time, if you are ready to cook, homemade recipes can be helpful. Its better to avoid raw chicken and stick with only cooked homemade cat food instead.

Raw Food Rules For Cats

There are two main rules for feeding cats. When you follow these, youre working with the cats natural nutritional patterns.

  • Feed your cat nose-to-tail animals that are smaller than they are . This includes bones, muscles, and organs especially the heart.Be careful about giving cats too much liver they can get vitamin A toxicity from liver. This recipe has a good amount you want it to replicate what they would get if they were hunting in the wild: Muscle meat and liver/heart/kidney. If you can find small animals that is a more natural diet for a cat!
  • If your food is not fresh and raw, supplement with the essential amino acid taurine.
  • After seeing so much success with switching our cat Bob to a raw food diet for kidney disease, friends and family and readers have been asking me about a recipe for kittens and healthy cats.

    The only change to the Feline Kidney Care Raw Food recipe is that I used bone-in chicken in place of the beef, as it contains the healthy fats from the skin as well as bone bone that cats need to grow and maintain bone health. Cats with kidney disease need to limit their phospherous, but cats without kidney disease should NOT limit phosphorous and should include bones in the diet.

    Is this recipe enough taurine? I wasnt sure, since taurine in the chicken heart may degrade when its frozen, and my chicken hearts come frozen. Since taurine is so essential to cats, I sprinkle powdered taurine, 1 pinch, on each container of his food .

    Fish Oil For Cats With Dry Skin

    Cat and Dogs with Kidney Disease

    Supplementing cats diets with fish oil to combat dry and itchy skin conditions like flea allergy dermatits and atopic dermatitis has been a subject of veterinary research since the 1990s. In 2010 a small study on 14 cats found that a diet supplemented with fish oil can reduce skin inflammatory responses in cats with allergies, especially when combined with flaxseed oil.

    However, a study submitted to the Veterinary Record in 1993 suggested that fish oil by itself was not enough to resolve miliary dermatitis . Although when combined with evening primrose oil, it was.

    Understanding The Causes And Treatment Options

    In addition to learning how to identify the signs of kidney disease in cats, you should also familiarize yourself with some of the underlying causes, so you know if your cat is at-risk or not.

    Acute kidney disease can happen at any time, but chronic kidney disease tends to affect older cats. In fact, as many as 3 in 10 senior cats develops this condition. Age increases your cats risk for kidney disease, but his risk is particularly high after the age of 9 years. This condition is also more common in certain breed types such as Persians, Chinchillas, and Exotics.

    Other risk factors for kidney disease in cats may include the following:

    • Kidney infection
    • Bad breath, often with oral ulcers
    • Pale gums, indicating anemia
    • Ocular hemorrhage or blindness

    Once your veterinarian has confirmed a diagnosis of kidney disease, the next step is to identify the cause and to determine a course of treatment.

    Acute kidney disease is often the result of an injury to the kidneys. This can be caused by the ingestion of a toxic substance, physical trauma, a severe infection, blocked blood flow to the kidney, or heart failure that reduces circulation. Chronic kidney disease is often related to untreated kidney infections and other chronic conditions that progress over time.

    Keep reading to learn more about dietary recommendations for the management of kidney disease.

    Below Is My Holistic Approach To Ckd In Cats:

    • Diagnostics. When your cat reaches 7-8 years of age starting monitoring blood work regularly. Be sure your veterinarian is checking your kittys thyroid and kidney function. for cheat sheet of laboratory values that we monitor for kidney function. If your kittys lab work indicates any signs of kidney disease, begin monitoring every 3-6 months.
    • Diet. Water is key here. Cats are notorious for poor water drinking! The more moisture you can put in your cats diet the better. Generally, a raw or canned diet will have the most moisture. Avoid dry food at all cost.

    Protein content is a major source of debate between allopathic and integrative veterinarians. The idea behind protein restriction is that you stress the kidneys less and build up less toxins in the bloodstream. While this may be true, cats as a whole are much healthier on a high protein, low carbohydrate diet. For this reason, many integrative veterinarians recommend normal amounts of protein in the interest of the whole cat, not just kidney function.

    I see both sides, and generally give my clients the option to feed either. For my cat, Sammy, I continue to feed a high protein diet.

    Supplements. Let me start by saying, many cats wont take any supplements. So, I have listed in order of importance the ones I recommend for chronic kidney disease:

    • Fish Oil. I use high doses of fish oil to help reduce inflammation and recommend Ultra EFA.
