Feline vaccinations are essential for protecting cats from various infectious diseases. Vaccines stimulate the cat's immune system to recognize and fight off specific viruses and bacteria. Common vaccines include those for feline viral rhinotracheitis, calicivirus, and panleukopenia, often referred to as the FVRCP vaccine. Regular vaccinations help prevent serious health issues and can be required for travel or boarding. Kittens typically receive their first vaccinations at around six to eight weeks of age, with booster shots given as they grow. It's important for cat owners to consult with a veterinarian to determine the appropriate vaccination schedule for their pets.
