Kidney (renal) disease is common in cats with at least 1 in 3 cats and 1 in 10 dogs likely to develop some form of kidney disease in their lifetime. And the likelihood of an occurrence increases with age.
Age really makes a difference with kidney disease. While previous studies have found 1 in 3 cats are likely to develop kidney disease in their lifetime, further research has shown CKD Stage 1 and 2 can occur in up to 50% of all cats, and over 80% in cats 15yrs or older.
CKD is one of those diagnoses that hits hard, especially because cats are so good at hiding when something’s wrong. By the time symptoms show up, a lot of kidney function may already be gone—sometimes up to 75%. But here’s the good news: with the right care at home, many cats with CKD can live happy, comfortable lives for years.
“Based on published evidence, feeding a therapeutic renal food is the single most effective treatment for improving survival and quality of life in cats (and dogs) with CKD.”
The first step is working closely with your veterinarian. Every cat is different, and your vet will help you build a care plan tailored to your cat’s needs. That might include:
If your cat’s appetite is dropping off or they seem dehydrated, those are things to bring up right away. Little changes can make a big difference.
Let’s be honest—feeding a CKD cat can be a challenge. They may be picky, nauseated, or just not interested in what’s in the bowl. But keeping them eating is one of the most important parts of managing this condition.
Even if you’ve been told about a “perfect” kidney diet, it doesn’t help if your cat won’t touch it. The most important rule:
Whatever they’ll eat, they should eat—especially if it’s moist, fresh, and balanced.
CKD affects your cat’s ability to hold onto water, which leads to dehydration. Moisture-rich foods—like raw or gently cooked diets—can help keep your cat hydrated and feeling better.
Dry food just doesn’t cut it here. It only has about 10% moisture. Compare that to raw or fresh food, which usually has around 70–75%. That difference can go a long way in supporting kidney function.
If you’re looking for a balanced, fresh diet made specifically for your cat’s condition, Fetching Foods is a great option. They create custom raw or gently cooked diets based on your veterinarian’s recommendations, including for cats with CKD.
Their meals are tailored to support hydration, control phosphorus and sodium, and use high-quality proteins—while also being something your cat actually wants to eat.
Proteins We Offer:
Chicken, Turkey, Venison, and Boneless Rabbit are popular proteins enjoyed by many cats and are kidney friendly. We also offer exotic (novel) proteins from alligator to ostrich and many different texture choices to match any preference.
Feeding the right diet is one of the best things you can do—and it doesn’t have to be complicated.
When your cat is well-hydrated, everything works better. They feel better, they eat better, and they’re more alert.
You can’t really “make” a cat drink more water—but you can feed them water. That’s why moisture-rich food is such a big deal in CKD care. In fact, with the right diet, you might even be able to delay or avoid giving subcutaneous fluids at home (though they’re sometimes still needed).
Take time each day to physically feel your cat—not just petting, but gently running your hands over their body to check muscle tone, hydration, and coat condition. A healthy skin and coat—smooth, soft fur and supple, elastic skin—can be good signs of hydration and overall well-being. On the other hand, dull, dry fur or flaky skin may point to dehydration or nutritional deficiencies.
This daily check-in can also help you spot weight loss early, which is common in CKD cats and often goes unnoticed under long or thick fur.
Part of managing CKD at home is just keeping an eye on the little things. Over time, you’ll get a feel for what’s normal for your cat and what isn’t.
Here are a few signs to track:
Keep a small notebook or use your phone to jot down changes. It’ll help you catch patterns early and give your vet a clearer picture.
Here’s a simple list to guide your day-to-day care:
CKD isn’t curable—but it is manageable. With a little routine, the right food, and regular support from your vet, your cat can enjoy a happy, comfortable life.
This diagnosis doesn’t mean it’s over—it just means you have a new path to follow together. One step at a time.
