Blood when a cat sneezes can come from nasal irritation or injury, but it may also signal infection, a foreign object, dental disease, toxin exposure, a clotting problem, or another illness. Contact a veterinarian promptly for advice; seek emergency care if bleeding does not stop, breathing is difficult, or toxin exposure is possible.
Keep your cat calm, do not put anything into the nostrils, and do not give medication unless a veterinarian advises it. Blood during sneezing is a symptom, not a diagnosis, and its appearance alone cannot identify the cause.
Key takeaways
- Possible causes include trauma, infection, foreign material, dental disease, toxins that affect clotting, tumors, and systemic illness.
- Contact a veterinarian promptly after blood appears with sneezing.
- Keep your cat calm. If tolerated, a wrapped cold pack may be held gently on the bridge of the nose without obstructing breathing.
- Do not insert cotton swabs or other material into the nostrils, and do not give medication unless a veterinarian directs you.
- Bleeding that does not stop, difficulty breathing, or possible toxin exposure warrants emergency veterinary care.
Is a cat nosebleed an emergency?
Seek emergency veterinary care if bleeding does not stop, your cat has difficulty breathing, or toxin exposure is possible. Contact a veterinarian promptly for advice and an appointment if your cat sneezes blood or seems painful.
A small episode that stops does not identify or rule out the cause. Call your veterinarian and describe what happened rather than assuming it was a simple cold.

What should you do when your cat sneezes blood?
While contacting a veterinarian, keep your cat calm and avoid disturbing the nasal passages.
- Keep your cat calm. Reduce noise and handling as much as possible.
- Keep material out of the nostrils. Do not insert cotton swabs, tissue, or other absorbent material into the nasal passages.
- Consider a wrapped cold pack. If your cat tolerates it and can breathe normally, hold a cold pack wrapped in cloth gently on the bridge of the nose. Stop if your cat becomes distressed, and do not obstruct the nostrils or mouth.
- Give no medication unless a veterinarian advises you to. VCA’s feline nosebleed guidance says, “Do not give your cat any medication unless your veterinarian advises you to do so.”
- Call a veterinarian promptly. Explain the bleeding and ask whether your cat needs an appointment or emergency care.
What information should you record for the veterinarian?
Note when the bleeding began, whether it has stopped or restarted, and any possible injury, toxin exposure, pain, or breathing difficulty. Photos of the discharge may help the veterinarian assess what happened.

Why is my cat sneezing blood?
Blood with sneezing may be a nosebleed or blood-tinged nasal discharge. Possible causes include trauma, infection, a foreign object, dental disease, toxins that affect clotting, nasal tumors, and systemic illness. These are possibilities, not a diagnosis; a veterinarian must assess the individual cat.
| Possible cause | What may be relevant | What to do |
|---|---|---|
| Trauma or irritation | Recent injury or irritation may be part of the history. | Tell the veterinarian about any suspected injury and seek emergency care if bleeding does not stop or breathing is difficult. |
| Infection | Upper-respiratory and fungal infections are among the possible causes. | Contact a veterinarian; blood alone cannot establish that an infection is responsible. |
| Foreign object | A foreign object may irritate or injure the nasal passage. | Do not try to remove or flush anything from the nose; ask a veterinarian for advice. |
| Dental disease or nasal tumor | Both are among the possible causes of feline nosebleeds or bloody nasal discharge. | A veterinarian can examine your cat and decide whether further testing is needed. |
| Toxin exposure or systemic illness | Rodenticide exposure and conditions affecting clotting are possible concerns. | Possible toxin exposure warrants emergency veterinary care. |
VCA identifies trauma and infection as common causes of feline nosebleeds and also lists rodenticide exposure, liver failure, feline leukemia virus, feline immunodeficiency virus, and disseminated intravascular coagulation among other possibilities. PetMD also lists foreign objects, tumors, and dental disease. These lists are not a way to diagnose a cat at home.
Can a URI cause blood in a cat’s sneeze?
An upper-respiratory infection is one possible cause of sneezing and nasal discharge, which may be blood-tinged. However, blood does not prove that a respiratory infection is responsible. Contact a veterinarian, especially if your cat seems painful or has other concerning signs.

When do persistent signs need more investigation?
Tell the veterinarian if bloody sneezing recurs or if nasal discharge persists. The history and examination can help the veterinarian decide whether additional testing is appropriate; a particular pattern does not establish a diagnosis by itself.
What will the veterinarian check?
The veterinarian will take a history and examine your cat, then choose any further tests based on the findings. Possible evaluations include blood or urine testing, imaging, rhinoscopy, biopsy, or nasal lavage. Not every cat needs every test.
How is bloody sneezing treated?
Treatment depends on the cause identified by the veterinarian. Do not give medication, flush the nose, or try to remove suspected material yourself. A veterinarian may recommend supportive care or further treatment after examination and, if needed, testing.
