Feline Calicivirus (FCV) is one of the most common respiratory infections in cats, particularly contagious in multi-cat households, catteries, or stray cat populations. While most cases recover, certain strains can cause severe symptoms and even be life-threatening. As a cat owner, understanding the early signs of FCV and preventive measures can help protect your feline companion from infection.
