Renal & Oxalate is specially formulated to meet the requirements of cats with chronic renal failure. The diet is limited in protein and phosphorous, which prevents the accumulation of waste, reduces the stress on the kidneys and ultimately slows down the progression of renal failure. The proteins used are of high quality, in order to meet the amino acids requirements, without leading to excess waste products. Renal & Oxalate's energy density reduces food volume, to help animals with a loss of appetite to meet their daily energy requirement. The use of potassium citrate has a urine pH-increasing effect, which reduces the excretion of calcium in urine. In addition, citrate is able to bind calcium, which can reduce the occurrence of calcium oxalate formation in urine.
