Cause

• Damaged vessels in the nasal passage most often cause nosebleeds in cats. Other causes include trauma, foreign bodies in the nose, dental disease, nasal tumors and infections.
  
  

Veterinarian

• Your cat should see a veterinarian if it has a nosebleed. An emergency visit, however, is likely not necessary if you can get the bleeding to stop at home.
  
  

First Aid

• Keep the cat calm. Apply an ice pack or cold compress to the bridge of the cat's nose to slow bleeding.
  
  

Diagnosis

• Your veterinarian will conduct several ests to determine the cause of the cat's nosebleed. These may include blood tests, urinalysis, X-rays and further examination under general anesthesia.
  
  

Treatment

• Treatment will depend upon the cause of the nosebleed. In cases of trauma, the nosebleed usually stops on its own. If the cause is a tumor, necessary treatment may include surgery and chemotherapy.
