Understanding Hematuria in Cats: Causes and Treatment Options

If you’ve ever noticed blood in your cat’s urine, you know just how alarming it can be. Hematuria, as it’s known in the veterinary world, can be a sign of underlying health issues. It’s important to understand the causes and treatment options for this condition to ensure your feline friend receives the best possible care. From Pandora Syndrome to urinary tract injuries, there are several potential factors to consider. In this article, beacon pet.com will break down the common causes of hematuria in cats and provide insights into the diagnostic process. We’ll also explore the various treatment options available and discuss preventative measures to keep your cat’s urinary health in tip-top shape.

Common Causes of Hematuria in Cats

Hematuria, which is the presence of blood in a cat’s urine, can be a cause for concern as it may indicate underlying health issues. There are several common causes of hematuria in cats, including:

Common Causes of Hematuria in Cats

Pandora Syndrome (Feline Lower Urinary Tract Disease)

One common cause of hematuria in cats is Pandora Syndrome, also known as Feline Lower Urinary Tract Disease (FLUTD). This is a collective term used to describe a variety of urinary tract disorders that cause inflammation and irritation.

Urethral Obstruction

Another potential cause of hematuria in cats is urethral obstruction. This occurs when a blockage, such as a urinary stone or a plug of mucus, obstructs the urethra and prevents the normal flow of urine. Urethral obstructions can be life-threatening and require immediate veterinary attention.


Constipation can also lead to hematuria in cats. When cats are constipated, they may strain to defecate, which can put pressure on the urinary tract and cause blood in the urine.


In some cases, tumors in the urinary tract can lead to hematuria in cats. These tumors can be either benign or malignant and may require further diagnostic testing, such as biopsies, to determine the appropriate course of treatment.

Congenital Abnormalities

Some cats may be born with congenital abnormalities that can cause hematuria. These abnormalities can affect the structure or function of the urinary tract, leading to blood in the urine.

Urinary Tract/Spinal Cord Injuries

Injuries to the urinary tract or spinal cord can also result in hematuria. Trauma, such as a fall or accident, can cause damage to the urinary system, leading to blood in the cat’s urine.

Recognizing Hematuria in Cats

Recognizing the presence of hematuria in cats is crucial in order to seek prompt veterinary care. Here are some key signs to watch out for:

Recognizing Hematuria in Cats


In addition to visible blood in the urine, other symptoms that may be present include frequent urination, straining to urinate, crying or vocalizing during urination, and urinating outside the litter box. It is important to monitor your cat’s behavior and look out for any changes that could be indicative of hematuria.

Observing Urine Color

One of the most obvious signs of hematuria is a change in the color of your cat’s urine. The urine may appear orange or red-tinged, which is a clear indication of the presence of blood. Close observation of your cat’s litter box can help you identify any changes in urine color.

Noticing Blood Clots

In some cases of hematuria, blood clots may be visible in your cat’s urine. These clots can range in size and may indicate a more serious underlying condition. If you notice blood clots in your cat’s urine, it is important to seek veterinary attention immediately.

Importance of Veterinary Consultation

If you notice blood in your cat’s urine, it is important to consult with a veterinarian as soon as possible. Prompt action can help identify and address the underlying cause of the hematuria, preventing further complications. Here’s why seeking professional advice is crucial:

Importance of Veterinary Consultation

Prompt Action

Early detection and treatment of hematuria can be critical in ensuring the well-being of your cat. Delaying veterinary consultation could potentially lead to worsening of the condition and additional health complications.

Seeking Professional Advice

A veterinary consultation is necessary to determine the cause of the hematuria and develop an appropriate treatment plan. Only a qualified veterinarian can conduct the necessary tests and examinations to accurately diagnose the underlying cause of the blood in your cat’s urine.

Diagnostics for Hematuria

To determine the cause of hematuria in cats, veterinarians often perform a range of diagnostic tests. These tests help identify any underlying conditions and guide the appropriate treatment options. Here are some of the diagnostics commonly used:

Diagnostics for Hematuria in cat

Physical Exams

During a physical exam, the veterinarian will carefully examine your cat, looking for any signs of pain or discomfort. They may also palpate the abdomen and urinary tract to check for any abnormalities.


Bloodwork is an essential diagnostic test that can provide valuable information about your cat’s overall health. It can help identify any underlying systemic conditions that may be contributing to the hematuria.


A urinalysis involves analyzing a sample of your cat’s urine to assess its composition and properties. This test can provide information about the presence of red and white blood cells, crystals, bacteria, and other substances that may indicate the cause of the hematuria.

Urine Culture and Susceptibility Tests

If a urinary tract infection is suspected as the cause of the hematuria, a urine culture and susceptibility test may be performed. This test helps identify the bacteria responsible for the infection and determines the most effective antibiotic treatment.

Imaging (X-rays and Ultrasound)

Imaging techniques such as X-rays and ultrasound can be used to visualize the urinary tract and identify any abnormalities, such as bladder stones or tumors. These tests provide a detailed view of the urinary system, aiding in diagnosis and treatment planning.

Treatment Options for Hematuria

The treatment for hematuria in cats depends on the underlying cause. Once the cause has been identified through diagnostic testing, the veterinarian will recommend the most appropriate treatment options. Here are some common treatment approaches:

Treatment Options for Hematuria

Pain Medication

If your cat is experiencing discomfort or pain due to hematuria, the veterinarian may prescribe pain medication to alleviate their symptoms and improve their overall well-being.

Diet Changes

In certain cases, changing your cat’s diet may help manage or prevent hematuria. Specialized prescription diets that promote urinary health can be beneficial for cats with urinary tract issues.

Increased Water Intake

Encouraging your cat to drink more water can help dilute their urine and decrease the risk of urinary tract problems. Providing fresh water in multiple locations and using fountains or bowls that appeal to your cat’s preferences may help increase their water intake.

Fluid Therapy

Fluid therapy may be recommended to help address dehydration and maintain proper urinary tract function. Intravenous or subcutaneous fluids may be administered by the veterinarian to ensure adequate hydration.

Anti-Spasmodic Medication

If your cat’s hematuria is caused by urethral spasms, anti-spasmodic medication may be prescribed. These medications help relax the muscles in the urinary tract, reducing pain and irritation.

Stress Reduction Techniques

Stress can contribute to urinary tract issues in cats. Implementing stress reduction techniques, such as providing a calm and enriching environment for your cat, can help alleviate stress and decrease the likelihood of recurring hematuria.


If a urinary tract infection is identified as the cause of the hematuria, a course of antibiotics will be prescribed to treat the infection. It is essential to follow the prescribed dosage and complete the full course of antibiotics.

Prescription Diets

In some cases, specialized prescription diets may be recommended to manage and prevent urinary tract problems. These diets are formulated to promote urinary health and minimize the risk of conditions that can lead to hematuria.

Surgical Removal of Bladder Stones

If bladder stones are causing the hematuria, surgical removal may be necessary. The veterinarian will discuss the procedure and options with you and determine the best course of action for your cat.

Preventative Measures for Hematuria

Taking preventative measures can help reduce the likelihood of your cat experiencing hematuria. By implementing the following practices, you can promote your cat’s urinary health:

Preventative Measures for Hematuria

Monitoring Behavior and Elimination Patterns

Keep an eye on your cat’s behavior and litter box habits. Take note of any changes, including increased frequency of urination or difficulty urinating. Early detection of any abnormalities can help prevent complications.

Promoting Exercise and Healthy Weight

Regular exercise and maintaining a healthy weight can contribute to your cat’s overall well-being, including their urinary health. Encourage playtime and provide opportunities for physical activity to prevent obesity and related health issues.

Increasing Water Intake

As mentioned earlier, increased water intake can help dilute the urine and reduce the risk of urinary tract problems. Consider incorporating wet food into your cat’s diet or using water fountains to entice them to drink more water.

Creating an Enriched Environment

Stress can play a significant role in urinary tract health. Create an enriched environment for your cat by providing mental stimulation, hiding spots, scratching posts, and interactive toys. This can help reduce stress levels and promote their well-being.

Reducing Stress

Minimize stressors in your cat’s environment as much as possible. Avoid sudden changes, provide a calm and predictable routine, and create designated safe spaces where your cat can retreat to when they need some quiet time.

Properly Setting Up Litter Boxes

Ensuring that your cat’s litter boxes are set up correctly can help prevent urinary issues. Provide multiple litter boxes in accessible locations, use unscented litter, and clean the boxes regularly to maintain a clean and inviting environment for your cat.

By implementing these preventative measures, you can help keep your cat’s urinary health in check and reduce the risk of hematuria.

In conclusion, hematuria in cats can be caused by various factors, ranging from urinary tract infections to congenital abnormalities. Early recognition, prompt veterinary consultation, and thorough diagnostics are essential for determining the underlying cause and providing appropriate treatment. By taking preventative measures and promoting overall health and well-being, you can reduce the likelihood of your cat experiencing hematuria and urinary tract issues. Always consult with a veterinarian for guidance and support regarding your cat’s urinary health.
