Cat nose bleeding may be caused by trauma, foreign matter in the nasal cavity, viral infection, or tooth inflammation. It is best to check whether the cat has trauma or foreign matter in the nasal cavity. If there is trauma or foreign matter, It must be treated in time to avoid wound infection and inflammation; if there is no trauma, check whether the cat’s teeth are red and swollen. If not, it is best to take the cat to the pet hospital for examination and treatment to avoid delaying the condition.
