Causes

• Feline herpes or feline calicivirus causes almost 90 percent of feline flu cases. The virus can be passed from a mother cat to a kitten or be transmitted from other infected cats or objects that have come into contact with the virus.
  
  

Considerations

• Certain cats are more vulnerable to catching feline flu. For example, cats that are in overcrowded facilities such as shelters or pet stores are more susceptible.
  
  

Symptoms

• According to Marvista Vet, common symptoms of feline flu include a cough, fever, red eyes, sneezing and nasal discharge. Feline flu can also cause ulcers around the mouth or nose. The first outbreak of feline flu is usually the most severe. Once a cat has recovered, its immune system should be able to keep the virus in check.
  
  

Warning

• In addition to feline herpes or feline calicivirus, cats also can suffer from other forms of influenza. A 13-year-old Iowa cat was infected with what was believed to be the first case of H1N1 in a cat, according to Time magazine.
  
  

Vaccinations

• Vaccinations against the feline flu are available. Pet owners should discuss these options with a veterinarian.
