What's the best cat food to prevent kidney disease in healthy cats?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 6 years and 2 months old | 11 lbs

My best friend's cat (11 yrs old) has rec'd a diganosis of EARLY stage CKD. Vet was very concerned with high levels of phosphates and now I am concerned about my cats nutrition as it sounds that high protein/phosphates are the culprit in some cats. My cat is healthy so far. Fed Blue Buffalo Wildnerness Salmon (40% protein, 1.47 phosphates). I want to be proactive to circumvent the potential of CKD with her. Suggestions/advice needed for optimum food for her.

Hello, and thanks for your question about Stella. I can tell you want to make sure you're making the best decisions in her care! In short, if a cat doesn't currently have kidney disease, no diet change is likely to *prevent* it from developing. It's an age-related disease, so if her current kidney function is fine you don't have to make any changes. However, Blue Buffalo isn't my favorite food - I see a lot of cats with urinary problems on this diet, and a lot of animals with chronic GI problems. I prefer Hills Science Diet, Purina, or Royal Canin instead. The best way to be proactive about managing the possibility of CKD is through regular routine bloodwork to get a good baseline of what's "normal" for Stella, in order to pick up on any changes as early as possible. I recommend doing this annually as long as results keep coming back normal, and increase the frequency if your vet sees something worth monitoring. Hope this helps!
