Feline Viral Rhinotracheitis. The term “rhinotracheits” means inflammation of the nose and trachea. When the infection is active, a cat can show symptoms for 5 to 20 days in mild cases and up to 6 weeks in severe cases.
Virus could be successfully transmitted between shedding carrier cats and unrelated susceptible kittens, but only if there was intimate contact between them. Feline viral rhinotracheitis (sometimes referred to as feline influenza or feline pneumonia) can affect all wild and domestic cats. This condition affects the youngest mostly, and it can even lead to death.
