What Can You Feed a Cat With Kidney Disease?

As a cat owner, it’s important to pay close attention to your feline’s diet and nutrition. When your cat has kidney disease, their dietary needs may change in order to support their health and manage their condition. Here is a list of what you can feed a cat with kidney disease:

  1. Prescription kidney diet: If your cat has been diagnosed with kidney disease, your veterinarian may recommend a prescription kidney diet. These diets are formulated with reduced levels of protein and phosphorus, which can help to manage the symptoms of kidney disease and slow its progression. Prescription kidney diets can be found in wet or dry form, and are usually available through your veterinarian or through online retailers.
  2. Low protein wet food: If your cat is not receptive to a prescription kidney diet, or if you prefer to feed them a more natural diet, low protein wet food can be a good option. Look for wet food brands that are formulated with high-quality protein sources and low levels of phosphorus. Some good options include Weruva, Merrick, and Ziwi Peak.
  3. Homemade diet: If you’re comfortable preparing your own cat food, a homemade diet can be a good option for a cat with kidney disease. Make sure to consult with a veterinarian or a veterinary nutritionist before starting your cat on a homemade diet, as it’s important to ensure that the diet is nutritionally balanced and meets your cat’s specific needs. Some good options for homemade kidney-friendly recipes include boiled chicken breast and white rice, or boiled turkey and sweet potato.
  4. Low phosphorus treats: While treats should not make up a significant portion of your cat’s diet, it can be nice to offer them a special treat now and then. If your cat has kidney disease, look for low-phosphorus treats that will not overload their kidneys. Some good options include freeze-dried chicken or salmon treats, or cooked chicken breast slices.
  5. Water: It’s important to encourage your cat to drink plenty of water when they have kidney disease, as this can help to flush toxins from their body and prevent dehydration. Make sure to always have fresh water available for your cat, and consider adding a water fountain to encourage them to drink more. You can also try adding a small amount of broth or water to their wet food to increase their fluid intake.

In summary, when it comes to feeding a cat with kidney disease, it’s important to choose a diet that is low in protein and phosphorus and high in high-quality ingredients. Prescription kidney diets, low protein wet food, and a homemade diet can all be good options. Make sure to consult with a veterinarian or a veterinary nutritionist before making any changes to your cat’s diet, and always monitor their weight and overall health to ensure that they are getting the nutrition they need.
