What is a component of the FVRCP vaccine for cats?

The FVRCP vaccine is specifically designed to protect cats against three main infectious diseases: Feline Viral Rhinotracheitis, Feline Calicivirus, and Feline Panleukopenia. The "C" in FVRCP stands for Calicivirus, which is included in the vaccine to help prevent this particular viral infection. Feline Calicivirus can cause respiratory disease and oral ulcers in cats, making vaccination essential for their health, especially in multi-cat environments such as shelters or catteries.

The other vaccines mentioned, such as those for Rabies, Bordetella, and Leptospirosis, serve different purposes and are not included in the FVRCP combination vaccine. Rabies is a separate vaccine often mandated by law, Bordetella is primarily for dogs although some specialized feline vaccines exist for it, and Leptospirosis is not a primary concern for cats. Hence, Calicivirus is accurately identified as a component of the FVRCP vaccine.
