Is Blood in Your Cat’s Urine a Sign of a Urinary Tract Disease?


1. Should You Be Worried If Your Cat Has Blood in Its Urine?

Yes, definitely. While a one-time trace of blood in your cat’s urine might not be an emergency, any sign of discolored or blood-tinged urine should not be ignored.

In most cases, bloody urine (also called hematuria) is a key warning sign of urinary tract problems in cats. These may include urinary tract infections (UTIs), bladder inflammation (cystitis), urinary stones, or even stress-related conditions. Early detection and treatment are essential to prevent serious complications, such as a blocked urethra or kidney damage.


2. What Are the Common Signs of Blood in a Cat’s Urine?

Sometimes, you won’t see bright red blood, but subtle changes in your cat’s behavior or urine can be a clue:

SymptomWhat It Means
Pink, orange, or reddish urineLight traces of blood or pigment changes
Dark red urine or visible clotsMore serious bleeding in the urinary tract
Frequent but minimal urinationStraining to urinate, a typical symptom of urinary issues
Meowing, hiding, or licking genitalsDiscomfort or pain when urinating
Peeing outside the litter boxAssociating the box with pain, a behavioral warning

3. What Causes Blood in a Cat’s Urine?

✅ The Most Common Causes Include:

Cause TypePossible Conditions
Urinary issuesBladder infection, cystitis, urethritis, urinary stones, tumors
Bacterial infectionEspecially in older cats or females with weakened immunity
Feline Lower Urinary Tract Disease (FLUTD)A group of stress-related urinary disorders
Physical traumaInjury from a fall, fight, or other impact
Stress or anxietyOften leads to sterile cystitis (inflammation without infection)
Crystals or stonesMay scratch or block the urinary tract, leading to bleeding

4. Is It Always FLUTD?

Not exactly. FLUTD (Feline Lower Urinary Tract Disease) is a broad term for various urinary symptoms, including:

  • Blood in urine
  • Straining to urinate
  • Frequent urination
  • Crying or discomfort during urination
  • Behavioral changes (like hiding or inappropriate urination)

Common causes under the FLUTD umbrella include:

  • Idiopathic cystitis (most common)
  • Bladder or urethral stones
  • Urethral blockage
  • Bacterial infections (less frequent in cats)

FLUTD is especially common in indoor cats aged 1–10 years, with overweight male cats and cats that drink little water being at higher risk.


5. Which Cats Are More Likely to Have Blood in Their Urine?

Risk FactorWhy It Matters
Male catsNarrower urethras, more prone to blockages
Overweight catsLower activity and hydration levels
Low water intakeConcentrated urine increases risk of crystals and irritation
Dry food diet onlyLess moisture compared to wet food
High-stress householdsMulti-cat homes or recent changes can trigger stress
Older cats or cats with historyWeakened urinary function increases risk

6. What Should You Do If Your Cat Has Blood in Its Urine?

✅ Call Your Vet ASAP—Especially If You Notice:

  • Blood in urine for more than 24 hours
  • Decreased urination or signs of blockage
  • Vomiting, lethargy, or other distress symptoms
  • History of urinary tract issues
  • Peeing in sinks, tubs, or random spots

⚠️ A urinary blockage (especially in male cats) is a medical emergency. It can lead to kidney failure and death within 24–48 hours if not treated.


7. How Is Bloody Urine Diagnosed in Cats?

Your veterinarian may recommend:

Diagnostic TestPurpose
UrinalysisChecks for blood, bacteria, crystals, pH levels
Microscopic examLooks for crystals, red/white blood cells, epithelial cells
Urine cultureIdentifies bacteria and suggests effective antibiotics
UltrasoundDetects bladder wall changes, stones, or inflammation
X-rays or contrast imagingHelps find the size/location of stones or obstructions
BloodworkAssesses kidney function and electrolyte balance

8. How Is Blood in a Cat’s Urine Treated?

Treatment depends on the underlying cause. Common options include:

✅ Medications:

  • Anti-inflammatory or pain relief meds (NSAIDs)
  • Antibiotics (only if infection is confirmed)
  • Anti-anxiety meds (for stress-related cystitis)

✅ Diet Adjustments:

  • Prescription urinary care diets (e.g. Hill’s c/d, Royal Canin Urinary)
  • Increase wet food intake or add water to meals
  • Encourage hydration through multiple water bowls or pet fountains

✅ Medical Interventions:

  • Catheterization or surgery (in case of urethral blockages or large stones)

✅ Environmental Changes:

  • Reduce stress—provide quiet, secure spaces
  • More litter boxes (at least one per cat plus one extra)
  • Clean boxes daily to encourage healthy bathroom habits
