Cat Flu

Cat flu is a virus, just like the flu virus in humans. It is part of a group of ailments called Feline Upper Respiratory Disease; and, according to the Pet Education website, the scientific name for the most common virus in this category is rhinotracheitis. The Our Happy Cat website notes that feline herpesvirus and feline calicivirus are the two most common causes. Cat flu affects the cat's respiratory tract, and symptoms can include mucus secretions from the eyes, nose and mouth. The cat flu is spread by contact with secretions, but keeping your cat up-to-date on its vaccinations can help it fend off the virus. Kittens are most susceptible to the cat flu.


According to the Our Happy Cat website, mouth ulcers can be a symptom of cat flu or of skin irritation. Either way, these sores sometimes secrete fluid. You must watch your cat's behaviour closely if you notice any mouth ulcers, as the sores may cause the cat to lose its appetite and become dehydrated.


Hives on a cat's face can develop because of allergic reactions to food or external objects, such as certain houseplants. The hives may secrete fluid or, if they are on the mouth, cause the cat to drool. Treatment for this allergic reaction is often steroids, but always discuss your options with your veterinarian before attempting treatment.


While cats will sometimes display symptoms similar to a cold in humans, it is important to monitor your cat closely when you notice anything out of the ordinary. Mucus discharge from the mouth, eyes and nose can often be a sign of serious illness that only your vet can diagnose. If you suspect an illness or allergic reaction has caused enough swelling in your cat's throat or mouth to inhibit its breathing, contact your vet immediately.
