Blood in a cat’s urine is a symptom, not a diagnosis. Several conditions can cause it, and the first thing to check is whether your cat can pass urine: repeated attempts that produce little or none may mean a life-threatening blockage and require emergency veterinary care now. If your cat is still urinating, contact a veterinarian promptly for advice and an examination.
First, check whether your cat can urinate
Watch what happens when your cat visits the litter box. Repeated straining or frequent attempts that produce only drops—or no urine—can indicate a urethral obstruction. Cornell’s Feline Health Center says, “A urethral obstruction is an absolute emergency, requiring immediate veterinary treatment.” Cornell’s guidance on feline lower urinary tract disease explains that a complete blockage prevents urine from leaving the body and can damage kidney function and disrupt fluid and electrolyte balance.

Obstruction is more common in male cats because their urethra is longer and narrower, but a female cat with these signs also needs urgent assessment. Do not wait to see whether the problem passes on its own; seek emergency veterinary care.
If your cat is passing urine but you see blood, contact a veterinarian promptly for triage. The appropriate timing depends on urine output and your cat’s overall condition; the veterinary sources cited here do not establish one safe waiting period for every cat. Crying while urinating, painful straining, or worsening behavior are reasons to seek urgent advice.

What can cause blood in a cat’s urine?
Blood in urine, frequent attempts, and straining can occur with several feline lower urinary tract conditions. Their signs overlap, so appearance alone cannot identify the cause.
Feline idiopathic cystitis
Feline idiopathic cystitis (FIC) is a common diagnosis when testing does not identify another cause. It can cause bladder discomfort, frequent attempts to urinate, and blood in the urine. “Idiopathic” means that a specific cause has not been identified. Stress may contribute, but bloody urine should not be assumed to be stress-related without veterinary assessment. Cornell’s FIC and lower urinary tract guidance notes that environmental enrichment and modification may help reduce the severity and frequency of FIC episodes.

Urinary stones
Stones can irritate the urinary tract and cause bleeding; depending on their location, they can also obstruct urine flow. A veterinarian may use imaging such as x-rays or ultrasound to look for stones. Treatment depends on what the examination and tests show.

Urethral plugs or obstruction
A plug or other blockage can prevent urine from passing. Stones are one possible cause of obstruction; plugs are another. Repeated unproductive straining is an emergency sign, not a way to determine the blockage’s cause at home.

Bacterial urinary infection
A bacterial infection is possible, but blood or other urinary signs alone do not prove that an infection is present. Merck Veterinary Manual’s overview of feline lower urinary tract disorders describes urinalysis and bacterial culture as likely tests when bacterial cystitis is suspected. Antibiotics are appropriate when a veterinarian diagnoses an infection, not simply because urine looks bloody.
Other conditions
Other possible causes include trauma and, less commonly, neoplasia (abnormal tissue growth). Merck’s overview includes neoplasia among potential causes of lower urinary tract disease, while VCA’s urinalysis guidance lists trauma and cancer among conditions associated with blood in urine. A veterinary examination is needed to investigate these possibilities.

How a veterinarian finds the cause
The veterinarian will generally start with a physical examination and urinalysis. Depending on the findings and your cat’s signs, further tests may include blood work, x-rays, abdominal ultrasound, or a urine culture. VCA’s explanation of urinalysis describes how urine testing helps assess urinary abnormalities; additional tests can help investigate causes such as stones or infection.

How treatment depends on the diagnosis
There is no single treatment for bloody urine because different conditions need different care.
- Obstruction: A veterinarian commonly restores urine flow with a catheter, often under sedation or anesthesia. Fluids and other treatment may be needed afterward. Cornell describes this approach in its lower urinary tract disease guidance.
- Confirmed bacterial infection: The veterinarian selects treatment based on appropriate urine testing; antibiotics are used when infection is diagnosed.
- Stones or FIC: Management depends on the specific findings and differs from treatment for infection or obstruction. A general “urinary” product is not a substitute for diagnosis.
Cornell notes that urinary-health diets may reduce the likelihood of obstruction for some cats with FIC, but there is no evidence that they reduce feline lower urinary tract signs themselves. Ask your veterinarian about diet after your cat has been assessed; do not switch diets or rely on supplements as a treatment for unexplained blood.
What to do at home while arranging veterinary care
No safe home remedy for bloody urine is established in the veterinary guidance cited here. Prioritize getting veterinary advice rather than trying to treat the symptom yourself.

- Note straining, crying, changes in behavior, and when you first noticed the blood.
- Seek emergency care immediately if your cat repeatedly tries to urinate but produces little or none.
- Do not give antibiotics or assume a retail urinary product, diet, supplement, or home test can identify or cure the cause.
If your veterinarian diagnoses FIC, discuss environmental changes that may help manage episodes. Cornell identifies environmental enrichment and modification as potentially helpful, while emphasizing that urinary-health diets do not by themselves reduce lower urinary tract signs.
