Cat Flu Symptoms

Like the "stomach flu" in human, the "cat flu" is actually a misnomer. Cat flu is not caused by the influenza virus. Instead, it refers to a syndrome that affects a cat's upper respiratory tract that is caused by two other, highly contagious viruses: the feline calicivirus (FCV) and feline herpesvirus (which casuses FVR). These viruses spread though cat-to-cat interaction or contact with exposed food, litter, or bedding.

  1. FCV infection

    • Symptoms of FCV include fever, mucus discharge from the eyes and nose, sneezing, hoarseness and ulcerations in the mouth.

    FCV joint pain

    • In some cats, widespread arthritic-type pain may present in multiple joints after a bout of FCV.

    FCV and secondaty infections

    • If a secondary bacterial infection develops, FCV can progress into pneumonia. Symptoms of pneumonia include labored breathing, lethargy, and dryness of nose and mouth.

    FVR symptoms

    • Infection with FVR causes coughing, sneezing, nasal discharges, fever, dry eyes, or loss of appetite.

    FVR and ulcers

    • Some cats develop pinpoint or dendritic ulcers on their corneas when infected with FVR.

    FVR and secondary infections

    • In most FVR cases, a cat allowed to rest and recuperate will recover within 4 to 7 days, however, any secondary infections can prolong the appearance of symptoms.

    Diagnosing

    • Veterinarians have to use specialized lab tests to diagnose different types of cat flu---especially since they share so many symptoms with other types of feline respiratory disease.
