The Feline Distemper Vaccine is designed to protect cats from a serious viral infection known as feline panleukopenia. This disease can cause severe gastrointestinal issues, immune system suppression, and can be fatal, especially in young kittens. The vaccine helps the cat's immune system recognize and fight the virus if exposed. Vaccination is typically recommended for all cats, especially those that are unvaccinated or at higher risk, such as outdoor cats. The vaccine is usually administered as part of a combination vaccine, which may also protect against other diseases like feline herpesvirus and feline calicivirus. Regular vaccination helps ensure a cat's long-term health.
