Discovering blood in your cat’s urine can be a distressing experience for any pet owner. This alarming sign, known as hematuria, can indicate various underlying health issues in your feline friend. In this article, we’ll delve into the possible causes, symptoms, and steps to take if you suspect your cat has blood in its urine.

What Is Hematuria?

Hematuria is a condition characterized by the presence of red blood cells in the urine. It can vary in severity, from subtle discoloration to urine that appears visibly bloody. While it’s important to remember that hematuria itself is not a diagnosis, it is a clear indication that something may be amiss with your cat’s urinary tract or overall health.

Common Causes of Hematuria in Cats

  1. Urinary Tract Infections (UTIs): Bacterial infections in the urinary tract can lead to inflammation and bleeding. Cats with UTIs may show increased frequency of urination, straining, or discomfort.
  2. Bladder Stones: The presence of stones in the bladder can cause irritation and bleeding. Cats with bladder stones may exhibit signs of pain during urination.
  3. Feline Lower Urinary Tract Disease (FLUTD): FLUTD is a collective term for various conditions that affect the bladder and urethra. It often presents with hematuria and can be triggered by stress, diet, or other factors.
  4. Trauma: Physical injury to the urinary tract, such as a fall or accident, can result in hematuria. It’s crucial to seek immediate veterinary care in such cases.
  5. Cancer: While less common, cancers of the urinary tract can lead to hematuria. It’s more prevalent in older cats.

Symptoms to Watch For

Apart from blood in the urine, cats experiencing hematuria may show other signs:

  • Frequent urination.
  • Straining to urinate.
  • Vocalization or signs of pain during urination.
  • Urinating outside the litter box.
  • Changes in urination habits, such as producing only small amounts of urine.

When to Seek Veterinary Care

If you notice any of the symptoms mentioned above, it’s essential to consult your veterinarian promptly. Early diagnosis and treatment can prevent further complications. Your vet will likely perform a physical examination, urinalysis, and possibly imaging tests to determine the underlying cause.

Treatment and Management

Treatment for hematuria depends on the underlying cause. It may include antibiotics for UTIs, dietary changes for FLUTD, or surgical intervention for bladder stones or tumors. Follow your veterinarian’s guidance closely and administer any prescribed medications as directed.


While not all cases of hematuria can be prevented, you can take certain measures to promote your cat’s urinary health:

  • Ensure your cat stays hydrated by providing clean, fresh water.
  • Feed your cat a balanced diet and consult your veterinarian for dietary recommendations.
  • Maintain good litter box hygiene to encourage regular urination.


The discovery of blood in your cat’s urine can be unsettling, but it’s a crucial indicator that something may be wrong. Prompt veterinary attention and a comprehensive evaluation are essential for identifying and addressing the underlying cause of hematuria. With proper care, many cats can recover from urinary issues and enjoy a healthy, happy life.
