Protein in Cat Urine
Listen to this article

Cats don’t always show signs of illness and pain. Even attentive pet owners can miss chronic kidney disease (CKD) and other disorders. Luckily, you can monitor your pet’s health at home with urine test strips to check for protein in cat urine.

Symptoms of Protein in Cat Urine

Elevated protein (proteinuria) in a cat's urine can signal kidney problems or infections. Consult a vet for diagnosis and treatment.

Proteinuria in cats is characterized by abnormal proteins or elevated protein in the urine [1].

Symptoms include [2]:

Symptoms of CKD and other conditions related to high protein in cat urine include [2]:

  • Excessive thirst
  • Fatigue
  • Loss of appetite
  • Swelling of the legs
  • Fluid in the abdomen

Causes of Protein in Cat Urine

Kidney infections in cats can cause [1]:

  • CKD: This is when the kidneys gradually lose the ability to filter acids and waste products from the bloodstream. This can cause abnormal metabolism, hypertension, and an inability to produce red blood cells [3].
  • Glomerulonephritis: This is when compounds produced by the immune system get trapped in small kidney structures called glomeruli. The buildup of toxins can lead to kidney failure and other illnesses [4].
  • Acute pancreatitis: This is characterized by inflammation of the pancreas. Symptoms include abdominal pain, decreased appetite, and lethargy [5].

These conditions require medical treatment, so consult your veterinarian immediately.

Gradual kidney function loss in cats, known as chronic kidney disease (CKD), can lead to increased thirst, weight loss, dehydration, vomiting, hypertension, anemia, and a decline in overall quality of life, but with proper veterinary care, its progression can be managed.

Testing for Protein in Cat Urine

Veterinarians use a cat urinalysis to test for high levels of protein. They collect the cat’s urine and assess its appearance and chemical composition [6].

Veterinarians measure the urine protein-to-creatine ratio to determine how much protein gets secreted through the urine. Excessive protein can indicate glomerular disease.

Caring for a Cat With Protein in Urine

Pancreatitis may be treated with antinausea drugs [5], while glomerulonephritis may require immunosuppressive medications [4].
