If you’ve just discovered your cat has kidney disease – you’re not alone. Chronic kidney disease is one of the most common conditions indoor cats will experience. The usual culprit is dehydration. As a result, the kidneys can’t properly filter down waste products. It causes a lot of urination, weakness, and loss of appetite.

The only way to confirm if your cat has kidney disease for sure is through an official test and diagnosis. Once you know your cat is struggling, it can feel worrisome and overwhelming as a cat parent to improve your cat’s condition. But we want to reassure you that it doesn’t have to be all downhill from here. 

The good news is nutrition and diet plays a key role in slowing the progression of kidney disease in your cat!

So it’s time to get good food that eases kidney strain and promotes renal function (acid-base balance). Here are some important products and considerations before you commit to purchasing. But always double check with your vet to ensure it’s right for your kitty.

Canned Wet Food is a Must

It’s crucial to boost your cat’s intake of water. In order to help your cat consume as much fluids as possible, consider switching to an all wet food diet. This will help the kidneys concentrate the urine effectively again.

Low levels of protein, phosphorus, sodium

Cat food that has lower levels of the above ingredients and minerals will reduce kidney strain. Decreased protein helps slow down kidney disease by alleviating work for the kidneys to excrete protein waste. Limiting phosphorus and sodium will also help reduce kidney impact and slow down the disease. These are the recommended ranges:

  • Protein: 28 – 35%
  • Phosphorus: 0.3 – 0.6%
  • Sodium: ≤0.4%

Healthy Fats

Yes – there is such a thing as healthy fats! Omega fatty acids are critical in your cat’s diet for maintaining low blood pressure and reducing inflammation. Look out for food that boasts omega-3 and omega-6 fatty acids.


All of the other factors don’t matter if your cat will barely touch the food. Of course, we can sometimes eat what we have to even if we don’t enjoy it. Cats, on the other hand, are notoriously picky. Ensure your cat has a liking to a particular food product before buying it in bulk!
