Diagnosing the Causes of Blood in Urine in Cats


The advent of blood in the pee of felines referred to as hematuria can be a problematic notice for pet proprietors. While it isn’t generally an indication of a natural condition, it is essential to have your feline assessed by a vet to decide the hidden reason. This article will examine the different reasons for hematuria in cats, just as the analytic tests that might be utilized to distinguish the hidden cause.

Clinical Signs

Hematuria in felines can vary from a few scarlet corpuscles to the nearness of copious measures of blood. The shade of the pee can go from pink to red or chestnut. Now and again, the nearness of blood may be so hidden that it is just obvious under a magnifying instrument. In other cases, the urine may be visibly bloody.

In addition to hematuria, cats may demonstrate other signs depending on the underlying cause. These signs can include pain while urinating, straining to urinate, increased frequency of urination, and licking of the genital area.

Diagnostic Tests

If your feline is displaying indications of hematuria, your vet will likely propose several diagnostic tests to discern the fundamental cause. These evaluations may comprise a urinalysis, a comprehensive blood count (CBC), a biochemical characterization, and imaging examinations such as radiographs (X-rays) or sonography.


A urinalysis is a useful diagnostic instrument that can furnish invaluable penetration into the well-being of an individual. It is ordinarily utilized to identify the nearness of contamination, aggravation, kidney illness, and different issues to screen the adequacy of treatment. Likewise, the test can recognize the nearness of unnatural substances, such as glucose, proteins, ketones, bilirubin, and blood cells. Urine tests are normally gathered in a sterile compartment and inspected under a magnifying instrument to distinguish the presence of any strange substances. A urinalysis result can help diagnose or rule out certain conditions and provide important information for further medical evaluation.

Complete Blood Count (CBC)

A thorough blood analysis (CBC) is an inspection that gauges the amount and varieties of cells in the blood. It can aid in distinguishing a hidden contagion or redness, which may be the source of hematuria. 

Biochemical Profile

A biochemical profile is an experiment that evaluates the concentrations of unusual substances in the blood, for example, electrolytes, proteins, and enzymes. It can aid in detecting an inherent metabolic abnormality, which may be the origin of hematuria.

Imaging Studies

Imaging modalities such as radiographs (X-rays) or sonography can aid in recognizing structural peculiarities in the urinary tract or kidneys, potentially elucidating the source of hematuria.

Common Causes of Hematuria in Cats

Once the results of the diagnostic tests are available, your veterinarian will be able to determine the underlying cause of hematuria in your cat. Some of the most common causes include:

Infection: Bacterial, viral, and fungal infections can cause hematuria in cats.

Inflammation: Swelling of the urinary tract or kidneys can engender hematuria. Various circumstances, including urinary tract contagions, kidney stones, and malignancy, can trigger this.

Trauma: Trauma to the urinary tract or kidneys can cause hematuria. Various factors, including physical trauma or exposure to toxins, can cause this.

Metabolic Disorders: Metabolic disorders like kidney disease and diabetes can cause hematuria.


The treatment for hematuria in cats will depend on the underlying cause. In some cases, antibiotics may be prescribed to treat an infection. Surgery may be necessary to remove a tumor or kidney stone in other cases. Sometimes, no treatment may be necessary if the cause is not serious.


Hematuria in cats can be an alarming sign for pet owners. Having your cat evaluated by a veterinarian to determine the underlying cause is important. Diagnostic tests such as a urinalysis, complete blood count (CBC), biochemical profile, and imaging studies can help to identify the underlying cause. Common causes of hematuria in cats include infection, inflammation, trauma, and metabolic disorders. The treatment for hematuria will depend on the underlying cause.
