Pet Proteinuria Symptom Guide | What to Watch For and When to Seek Care
Understand possible causes of Proteinuria and what to observe at home
Proteinuria may reflect altered kidney or urinary-system function. Continue observing urine amount and characteristics, record changes, and arrange veterinary assessment when needed.
What this symptom means clinically
Proteinuria means an abnormal amount of protein is present in the urine, often related to increased permeability of the kidney filtration barrier or impaired tubular reabsorption. It may also occur when excess blood proteins overwhelm kidney handling. Urinalysis helps assess kidney and urinary-system abnormalities and monitor trends.
🐱 In cats
In cats, Proteinuria is often associated with chronic kidney disease or glomerular disease, and persistent changes in older cats require regular monitoring.
🐶 In dogs
In dogs, Proteinuria may arise from glomerular or tubular problems or from systemic disease that changes blood protein levels; laboratory results are needed to identify the source.
