"This study evaluates the effect of dietary protein content on renal parameters in 23 healthy spayed female cats. The objective was to determine if cats eating diets high in protein will have higher serum urea nitrogen (UN) and creatinine values without a detectable change in kidney function, as assessed by urinalysis. [...] cats were randomly assigned to receive either a high protein [HP = 46% metabolizable energy (ME)] or low protein (LP = 26% ME) diet. [...] UN, albumin, alanine aminotransferase and urine specific gravity were significantly higher, and creatinine and phosphorus were significantly lower (P < 0.05) when cats were fed the HP diet as compared to when they were fed the LP diet, although none of the mean values were found to be outside of the corresponding reference interval. Dietary intake can result in clinically significant changes in UN and statistically significantly changes in several other biochemical analytes, although all analytes are likely to remain within normal reference intervals. Therefore, an accurate dietary history is necessary to help determine if renal parameters are being influenced by diet in a particular patient."

Although high-protein feeding can exacerbate clinical signs by leading to azotemia in animals with advanced renal failure, these effects occur because the loss of renal function leads to an accumulation in the blood of nitrogenous and nonnitrogenous end products of protein metabolism, not due to increased damage to the kidneys.
