Keeping your cat healthy starts with understanding when they need vaccinations. You might wonder, "How old do cats have to be to get shots?" This is a common question for new cat owners. Vaccinations protect cats from serious diseases and help them live longer, healthier lives.

In this guide, we’ll explain the ideal age for your cat’s first shots, the vaccination schedule, and why timely vaccinations are crucial. Knowing this information helps you plan vet visits and keep your cat safe from preventable illnesses.

Why Vaccinations Are Important for Cats

Vaccinations protect cats from infectious diseases that can be severe or even fatal. They stimulate the immune system to recognize and fight specific viruses and bacteria. Without vaccinations, cats are vulnerable to illnesses like feline distemper and respiratory infections.

Vaccinating your cat also helps prevent the spread of diseases to other cats and sometimes even humans. This is especially important if your cat goes outdoors or interacts with other animals.

• Vaccines protect cats from deadly diseases like feline panleukopenia, which can cause severe illness or death without vaccination.

• Vaccinated cats are less likely to spread contagious diseases to other pets in your home or neighborhood.

• Regular vaccinations reduce veterinary costs by preventing illnesses that require expensive treatments.

• Protecting your cat with vaccines supports public health by minimizing zoonotic disease risks.

Understanding why vaccines matter will help you stay committed to your cat’s vaccination schedule and overall health care.

When Do Kittens Typically Receive Their First Shots?

Kittens usually get their first vaccinations between 6 and 8 weeks of age. This timing balances the protection kittens receive from their mother’s antibodies and the need to build their own immunity. Early vaccinations help protect kittens during their most vulnerable stages.

Your veterinarian will recommend a vaccination schedule based on your kitten’s health, lifestyle, and risk factors. Starting vaccinations early ensures your kitten develops strong immunity before exposure to common diseases.

• Kittens younger than 6 weeks often still have maternal antibodies that can interfere with vaccine effectiveness.

• Starting vaccines at 6 to 8 weeks helps build immunity as maternal antibodies decline.

• Multiple vaccine doses are given every 3 to 4 weeks until kittens are about 16 weeks old for full protection.

• Early vaccination reduces the risk of life-threatening infections during kittenhood.

Consult your vet to create a vaccination plan tailored to your kitten’s needs and environment.

Core Vaccines for Cats and Their Schedule

Core vaccines are essential for all cats regardless of lifestyle. These vaccines protect against the most common and dangerous feline diseases. The typical core vaccines include feline panleukopenia, feline herpesvirus, and calicivirus.

The vaccination schedule usually starts at 6 to 8 weeks and continues with boosters until about 16 weeks. After the initial series, adult cats receive boosters every 1 to 3 years depending on the vaccine and risk.

• Feline panleukopenia vaccine protects against a highly contagious and often fatal viral disease.

• Feline herpesvirus and calicivirus vaccines prevent common respiratory infections that can cause chronic illness.

• Booster shots are necessary to maintain immunity and protect cats throughout their lives.

• Vaccination schedules may vary based on your cat’s health, age, and lifestyle factors.

Following the recommended core vaccine schedule is key to keeping your cat safe and healthy.

Non-Core Vaccines: When and Why They Matter

Non-core vaccines are given based on your cat’s risk of exposure to specific diseases. These vaccines are not required for every cat but may be important if your cat goes outdoors, lives with other cats, or travels.

Examples include vaccines for feline leukemia virus (FeLV) and rabies. Your vet will assess your cat’s lifestyle and recommend non-core vaccines accordingly.

• Feline leukemia vaccine is recommended for cats that go outdoors or live with infected cats to prevent a serious viral disease.

• Rabies vaccination is often required by law and protects against a fatal disease transmissible to humans.

• Non-core vaccines help protect cats in higher-risk environments or specific geographic areas.

• Discuss your cat’s lifestyle with your vet to determine which non-core vaccines are necessary.

Choosing the right non-core vaccines ensures your cat has tailored protection based on their unique risks.

What to Expect During Your Cat’s Vaccination Visit

When you take your cat to the vet for vaccinations, the vet will perform a health check first. This ensures your cat is healthy enough to receive vaccines. Sick or stressed cats may need to delay vaccination.

The vet will explain the vaccination schedule, possible side effects, and answer your questions. Vaccines are usually given as injections under the skin or in the muscle.

• A thorough health exam helps identify any issues that could affect vaccine safety or effectiveness.

• Your vet will provide a vaccination record to track your cat’s immunizations over time.

• Minor side effects like soreness or mild fever are common but usually resolve quickly.

• Serious reactions are rare, but you should monitor your cat and contact your vet if concerns arise.

Understanding what happens during vaccination visits helps you feel prepared and confident in caring for your cat.
