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.

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

Known for being a premium pet food company that comes highly recommended by veterinarians, Hill’s start goes far back. In 1948 Dr. Mark Morris, a veterinarian known for formulating some of the world’s first clinical veterinary diets, was contracted by Burton Hill of the Hill Packing Company in Topeka, Kansas. Originally, Dr. Morris licensed Hill to produce his pet food formulas. So they worked together to manufacture food for dogs with kidney disease under the name Canine k/d.
When cats have damage to kidney tissues, the kidneys cannot perform as well as before, like filtering and reabsorbing nutrients. The condition is not reversible, but progression may be slowed. Therapeutic foods for kidney conditions are designed to help reduce workload on the kidneys, enabling them to function more effectively. Cats with decreased kidney function may experience loss of appetite and their food intake might decline.
Hill’s nutritionists and veterinarians developed Hill’s Prescription Diet k/d clinical nutrition to help protect your cat’s vital kidney function, enhance appetite and increase food intake. This dry food is made with chicken and has an irresistible taste that your cat will love. In fact, the nutrition of Prescription Diet k/d is clinically proven nutrition to improve & lengthen quality of life.This prescription recipe from Hill’s fits all the requirements for a kidney disease-friendly diet.
It’s low in protein and phosphorus, without resorting to the use of meat by-products or unnamed meals. In addition, Hill‘s has researched the tastes of cats with kidney disease and adopted our unique EAT technology in pursuit of deliciousness. It is known as a highly reliable food such as recommended by US veterinarians as No.1.
What are owners saying? This product scores highly on both flavor and nutritional benefit, with most cats seeming to happily switch to Hill’s dry food, and see improvements in their blood test results. Despite some owners complaining about the price, this formula still gets trust from owners.
