Why Did My Cat Pee Blood

Finding blood in your cat’s urine is always worrying. It’s a clear sign that something’s not right and your cat needs attention. Sometimes it’s caused by stress or diet, but often it points to a medical problem that shouldn’t be ignored.

Below are the 6 main reasons why your cat may be peeing blood — and what you can do to help.

Quick Overview: Common Reasons Cats Pee Blood

Cause	Main Symptoms	What You Should Do
Urinary Tract Infection (UTI)	Frequent peeing, crying, pink urine	Visit vet — antibiotics often needed
Bladder Stones	Straining, tiny urine spots	X-ray or ultrasound; surgery may be needed
Feline Idiopathic Cystitis (FIC)	Blood without infection, stress signs	Reduce stress; vet medication
Kidney Disease	Tiredness, less appetite, dehydration	Blood/urine tests; long-term care
Trauma or Injury	Sudden after accident or fall	Urgent vet visit
Tumors or Growths	Continuous blood, weight loss	Diagnostic imaging; surgery possible

1. Urinary Tract Infection (UTI)

A UTI is one of the most common causes of blood in cat urine. It happens when bacteria enter the urinary tract, causing pain and inflammation.
You may notice your cat crying when urinating or straining with pinkish urine.
Treatment usually includes antibiotics and increased water intake.

2. Bladder Stones

When minerals build up in the bladder, they can form hard stones that irritate the bladder lining. This leads to bleeding and discomfort.
If untreated, stones can block urine flow, which is life-threatening.
Your vet will confirm using an X-ray or ultrasound and may suggest a special diet or surgery.

3. Feline Idiopathic Cystitis (FIC)

FIC is a stress-related bladder condition often seen in indoor cats.
Even without infection, cats may have bloody urine, frequent peeing, or excessive licking.
Reduce stress, keep routines steady, and encourage hydration.
Your vet might prescribe anti-inflammatory medication to ease pain.

4. Kidney Disease

Older cats are prone to kidney issues that can cause blood in urine due to reduced filtering ability.
Signs include lethargy, loss of appetite, and excessive drinking or urination.
A vet will do blood and urine tests to confirm the condition.
Early diagnosis and special kidney diets help slow down damage.

5. Trauma or Injury

If your cat recently fell, fought, or was hit, trauma could cause internal bleeding affecting the urinary tract.
Symptoms appear suddenly and always need urgent vet care.
Never try home treatments — your cat must be examined immediately.

6. Tumors or Growths

In rare cases, urinary tract tumors can cause persistent bleeding and weight loss.
You might see blood even without other symptoms.
Vets may use ultrasound, biopsy, or surgery for diagnosis and treatment.
