Excess Protein in the Cat's Urine




Proteinuria is most commonly treated on an outpatient basis. If a disease that affects the kidney's ability to process waste (e.g., glomerular disease) is found, a dietary change may be recommended. Conversely, if the cat's kidney is inflamed or there is a high risk for infection, antibiotics may be prescribed.


Living and Management


If the problem is determined to be glomerular disease, modifications in the diet have been proven to be extremely effective. The cat's diet will be reduced in its levels of protein and sodium, and enhanced with omega-3 fatty acids.


The cat should be monitored on an ongoing basis as there are rare, but serious complications that can occur such as edema, blood clots, high blood pressure, and progressive kidney disease.




All cats should have their urine tested when they visit the veterinarian to determine its composition and to identify any abnormalities. If abnormal levels of protein are found in the urine, the cat should be carefully monitored.
