What Vaccines Does My Kitten Need?
Welcoming a kitten into your home is a joyful, heartwarming experience - and the start of a lifelong bond. But along with the cuddles and playtime, your new feline friend needs a solid foundation of care. One of the most important steps? Vaccinations.
Vaccines are essential to protecting your kitten from serious - and sometimes life-threatening - illnesses. They play a vital role in keeping your pet healthy and also help prevent the spread of disease to other cats.
If you're feeling a little overwhelmed, don’t worry - here’s a simple guide to the core and non-core vaccines your kitten may need, plus a general timeline to help you stay on track.
Why Vaccines Matter for Kittens
Kittens are especially vulnerable to infection because their immune systems are still developing. Vaccines work by gently training their bodies to recognize and fight off certain viruses and bacteria - before they ever encounter the real thing.
In short, vaccines help your kitten build immunity, giving them a much stronger defense against common feline diseases. And by vaccinating your cat, you’re not just protecting them - you're also helping reduce the spread of disease in your local cat community.
Core Vaccines: What Every Kitten Needs
Core vaccines are recommended for all kittens, regardless of whether they’ll be indoor-only or outdoor explorers. These vaccines protect against the most common and dangerous feline illnesses:
1. Feline Panleukopenia (Distemper)
A highly contagious (and often deadly) viral disease that causes vomiting, diarrhea, and severe dehydration. This is one of the most critical vaccines your kitten will receive.
2. Feline Herpesvirus (FHV-1) and Feline Calicivirus (FCV)
These viruses cause upper respiratory infections, often referred to together as feline viral rhinotracheitis. Symptoms include sneezing, nasal discharge, eye irritation, and sometimes mouth ulcers. They’re very common, especially in multi-cat households or shelters.
3. Rabies
Rabies affects the nervous system and is fatal - and it can be transmitted to humans. Vaccination is legally required in many areas, and even indoor cats need protection, as rabies can be spread by the bite of an infected animal.
Non-Core Vaccines: Based on Lifestyle and Risk
Non-core vaccines aren’t necessary for every cat, but they’re recommended in certain situations, especially if your kitten will be around other animals or spend time outdoors.
1. Feline Leukemia Virus (FeLV)
FeLV weakens the immune system and can lead to cancer. It spreads through close contact like grooming or sharing food and water bowls. This vaccine is often recommended for kittens, outdoor cats, or those in multi-cat homes.
2. Bordetella bronchiseptica
A bacterial infection that can cause respiratory issues, especially in crowded or high-stress environments like shelters or boarding facilities.
3. Chlamydophila felis
This bacterium causes conjunctivitis (eye inflammation) and is most often a concern in catteries or rescue settings. Your vet may recommend it if your kitten is at higher risk.
The Typical Kitten Vaccination Schedule
Vaccination generally starts when kittens are around 6 to 8 weeks old, with boosters given every 3 to 4 weeks until about 16 weeks of age.
A typical schedule looks like this:
- 6–8 weeks: First round of core vaccines
- 10–12 weeks: Booster shots + possible non-core vaccines
- 14–16 weeks: Final boosters
- 1 year later: Booster shots (some may shift to every 3 years after this)
Your vet may adjust the schedule based on your kitten’s health, lifestyle, and specific risks.
A Healthy Start Begins with Vaccines
Getting your kitten vaccinated is one of the best things you can do to ensure a happy, healthy future together. While it might seem like a lot at first, your veterinarian will walk you through the process and help create a personalized plan.
By staying up to date on vaccinations and regular checkups, you’re giving your kitten a strong start and the best possible protection for the adventures ahead.
