Cornell Is Conducting a Dietary Trial for CKD in Cats

Chronic kidney disease (CKD) is a devastating illness that is common among cats, so experts have long been searching for a solution that can prevent the disease or at least slow its progression. You may have heard that dietary changes might help kitties who have been diagnosed with kidney disease. Well, Cornell wants to dig deeper to learn more about how diet can affect kidney health in cats, so they’re conducting a dietary trial that will hopefully shed light on what vets and pet parents can do to help more cats.

Cornell University College of Veterinary Medicine has posted information regarding a dietary trial for cats with CKD. The trial will include cats who have been diagnosed with chronic kidney disease, but they need to be in IRIS Stage 1 or 2.


IRIS guidelines help veterinarians and cat parents know how advanced the kidney disease is. It uses factors that include creatinine and SDMA blood tests, as well as UPC ratio (urine protein to creatinine) and blood pressure. There are four stages, so stages 1 and 2 are the earlier stages of the disease.   


Cats who participate in this dietary trial will eat one of three commercial diets formulated for increased digestibility. The cats will need to eat the diet that they are given for at least a month, and up to a year if they respond favorably. The diet will need to be fed exclusively, without any other treats or supplements given.   


Also, kitties who are enrolled in this trial will go through an initial appointment that includes an exam and tests, and will then have to go back to a vet for follow-up exams and tests at 3 months, 6 months, 9 months, and 12 months. And pet parents will track their kitties’ quality of life throughout the trial.


The ultimate goal is to see if certain diets, including those with a specially selected protein and natural anti-inflammatory nutrients, can help manage CKD in cats. Does a diet consisting of a hydrolyzed protein work at maintaining low protein levels in order to help prevent issues like muscle wasting associated with this disease? We’ll have to wait and see what the results of this trial will show, and we’re looking forward to learning more.
