Why Is My Cat Peeing Blood?

Few moments are as startling as discovering blood in your cat’s litter box. It’s a sight that can instantly raise alarm, leaving you wondering what could be wrong with your feline companion. While cats are experts at hiding discomfort, hematuria—blood in the urine—is a clear signal that something isn’t right. Whether it’s a minor issue or a sign of a more serious condition, understanding the potential reasons behind this symptom can help you take the right steps to support your cat’s health and comfort. At Lakeland Animal Clinic, we’re here to help guide you through this concerning situation.

 

What Causes Blood in a Cat’s Urine?

When a cat urinates blood, it usually indicates irritation or damage to the urinary tract. While this symptom can occur for a range of reasons, pinpointing the cause is critical for effective treatment. Below are some of the most common causes:

Urinary Tract Infections (UTIs)

UTIs occur when bacteria enter the urinary system, causing inflammation and discomfort. Cats with UTIs may strain to urinate, produce small amounts of urine, or urinate outside the litter box. In some cases, you may notice frequent trips to the litter box with little to no output. Older cats and those with underlying health conditions are particularly prone to UTIs. If left untreated, the infection can progress to the kidneys, leading to more severe complications.

Feline Lower Urinary Tract Disease (FLUTD)

FLUTD encompasses a group of conditions that affect the bladder and urethra in cats. This term includes idiopathic cystitis, bladder stones, and urethral obstructions. Hematuria is a common symptom of FLUTD, alongside difficulty urinating, vocalizing during urination, and frequent licking of the genital area. Stress is a significant trigger for idiopathic cystitis, a non-infectious bladder inflammation that commonly affects younger cats. Changes in routine, household dynamics, or even diet can contribute to stress-related FLUTD symptoms.

Bladder or Kidney Stones

Bladder or kidney stones form when minerals in the urine crystallize and harden. These stones can irritate the lining of the urinary tract, leading to bleeding. In severe cases, stones may block the flow of urine entirely, creating a medical emergency. Certain breeds, such as Persians, may be genetically predisposed to forming stones. Additionally, a diet high in magnesium or lacking in moisture can increase the risk.

Trauma or Injury

Trauma to the lower abdomen or urinary system can cause blood to appear in your cat’s urine. Whether it’s due to a fall, a car accident, or a fight with another animal, any injury to the urinary tract should be evaluated by a veterinarian.

When Is Blood in Urine an Emergency?

In some cases, blood in your cat’s urine signals a life-threatening emergency. If you notice your cat straining to urinate, crying out in pain, or producing no urine at all, they could have a urethral obstruction. This condition, more common in male cats, prevents urine from leaving the bladder, causing it to fill and potentially rupture. Urethral obstructions require immediate veterinary intervention.

Diagnostic Steps to Identify the Problem

Determining why your cat is peeing blood involves a thorough veterinary examination. Here’s what you can expect during a visit to the vet:

Physical Examination

Your veterinarian will perform a comprehensive physical exam to check for signs of pain, swelling, or discomfort. They will likely palpate your cat’s abdomen to assess the bladder and surrounding organs.

Urinalysis and Culture

A urinalysis is often the first diagnostic step to determine the cause of hematuria. This test analyzes the urine for blood, crystals, bacteria, and other abnormalities. If an infection is suspected, your veterinarian may perform a urine culture to identify the specific bacteria responsible.

Imaging Studies

X-rays or ultrasound may be recommended to detect bladder stones, tumors, or structural abnormalities. These imaging tools provide a clearer picture of the urinary system and help identify obstructions or injuries.

Blood Work

Blood tests can reveal underlying health issues such as kidney disease or imbalances in electrolytes. These results are critical for determining the overall health of your cat and guiding treatment decisions.

Treating Blood in Urine

Once the cause of hematuria is identified, your veterinarian will create a tailored treatment plan. The following are some of the most common approaches:

Medication

For cats with UTIs or inflammation, antibiotics and anti-inflammatory medications are often prescribed. These treatments help resolve infection and reduce discomfort, allowing your cat to return to normal activities.

Dietary Changes

If bladder stones are present, dietary adjustments may be necessary to dissolve the stones or prevent new ones from forming. Prescription diets specifically formulated for urinary health can lower the risk of mineral buildup.

Stress Management

For stress-induced FLUTD, reducing environmental stressors is a key part of treatment. This may involve creating a more predictable daily routine, providing enrichment activities, or using calming aids such as pheromone diffusers.

Surgical Intervention

In cases where bladder stones or tumors are causing significant issues, surgery may be required. Surgical removal of stones or masses can relieve symptoms and improve your cat’s quality of life.

How to Support Your Cat’s Urinary Health

Here are a few steps you can take to promote your cat’s urinary health and reduce the risk of hematuria:

• Ensure your cat has constant access to fresh, clean water. Wet cat food can also increase water intake, which helps flush out the urinary system.
• Keep your cat’s litter box clean and easily accessible. A dirty or overcrowded litter box may discourage your cat from urinating regularly, increasing the risk of urinary problems.
• Feed your cat a balanced diet that supports urinary health. Consult your veterinarian for recommendations on high-quality food designed for your cat’s specific needs.
• Schedule annual wellness exams to monitor your cat’s overall health and catch potential urinary issues early.
