Chronic kidney disease is characterized by structural and/or functional impairment of one or both kidneys persisting for more than 3 months. In cats, chronic kidney disease can frequently occur in animals aged over 9 years with an incidence of approximately 10%. Thirty-four client-owned, neutered cats, suffering from stage II-III chronic kidney disease and diagnosed according to the International Renal Interest Society guidelines were randomly assigned to receive either a control diet (n = 17) or a nutraceutical diet (ND; n = 17) for 90 days. Both diets were commercialized for management of CKD symptoms. The diets were identical except that the ND contained tablets that consisted of 60-80% hydrolysed proteins, 20-40% minerals and active substances, that are, Lespedeza spp. 0.0588%, Vaccinium macrocarpom 0.0371%, and Taraxacum officinale 0.0231%. No adverse effects were reported during this study. Both diets resulted in an improvement in CKD symptoms. After a 90-day evaluation, creatinine, blood urea nitrogen, total proteins, and aspartate aminotransferase significantly decreased in cats that received the ND. A significant decrease was also observed in urine turbidity score, color score, and total proteins in cats that received the ND. We have found that a ND based on Lespedeza spp., Vaccinium macrocarpon, and Taraxacum officinale improves key indicators of renal failure in cats affected by chronic kidney disease.
