Feline Calicivirus (FCV) is one of the most common contagious respiratory diseases in cats, causing symptoms ranging from oral ulcers to severe systemic illness. For multi-cat households or rescuers, understanding FCV prevention, proper care, and rapid testing (e.g., FCV Ag Rapid Test Kit) is crucial. This guide covers FCV transmission, prevention, cat care, and diagnostic methods.

1. Understanding FCV: Symptoms & Transmission

What is FCV?

FCV is a highly contagious RNA virus affecting cats, particularly kittens, unvaccinated cats, and immunocompromised felines.

Common Symptoms

• Mild cases:

  • Sneezing, nasal discharge, watery eyes

  • Oral ulcers (painful mouth sores, drooling, reduced appetite)

What is CPV?

CPV (Canine Parvovirus) is a highly contagious and potentially fatal viral disease that primarily affects puppies and unvaccinated dogs. The virus attacks a dog's digestive and immune systems, causing severe vomiting, bloody diarrhea, dehydration, high fever, and low white blood cell counts. Without prompt treatment, CPV has an extremely high mortality rate.

How CPV Spreads

CPV is transmitted through:

• Direct contact: Exposure to infected dogs' feces, vomit, or saliva.

• Indirect contact: The virus can survive in the environment for months, contaminating toys, food bowls, clothing, or floors.

• Human carriers: Owners or visitors may unknowingly bring the virus home on shoes or clothing.
