How old cat needs to be vaccinated?

Kittens typically receive their first vaccinations around 6 to 8 weeks of age or when their weight reach 1kg.  They usually receive a series of vaccinations every 3 to 4 weeks until they are about 16 weeks old. After that, adult cats generally need booster shots every years, depending on the vaccine and your veterinarian’s recommendations. It’s always best to consult your vet for a vaccination schedule tailored to your cat’s needs.
