Cat and Kitten Vaccination Schedule: What Shots Your Cat Needs and When

A cat vaccination schedule starts when a kitten is around 6 to 8 weeks old, the exact start depending on the kitten's health, its environment and the mother's vaccination status. From there, the core vaccine is repeated every 2 to 4 weeks until the kitten is at least 16 weeks old, usually three doses in total, with rabies given from 12 weeks of age. After the kitten series, your cat is vaccinated every year for life, rabies included. At our clinic the core booster and the rabies booster are given at two separate visits, six months apart, so your cat is seen every six months. The core vaccines every cat needs protect against panleukopenia, feline herpesvirus, calicivirus and rabies, and indoor-only cats need them too.

That is the short version. The exact dates depend on your kitten's age when you first bring them in, their health, and what the breeder or shelter may already have done. At our clinic we build the schedule around the individual cat, so the simplest next step is to call us with your kitten's age and we will map out what is due and when.

This guide covers the core and non-core cat vaccines, the kitten vaccination schedule step by step, how adult boosters work in Lebanon, and whether an indoor cat really needs shots.

Core vs Non-Core Cat Vaccines: What Every Cat Needs

Every cat vaccination schedule is built from two groups. Core vaccines protect against diseases that are serious, widespread, or a risk to people, so every cat receives them. Non-core vaccines are decided case by case, based on how and where the cat lives.

Core vaccines for all cats:

• Feline panleukopenia, a hardy virus that attacks the gut and bone marrow. It is often called feline distemper and is frequently fatal in kittens.
• Feline herpesvirus (FHV-1) and feline calicivirus, the two main causes of "cat flu": sneezing, runny eyes and nose, mouth ulcers, and fever.
• Rabies, fatal once symptoms appear, and a public health issue because it can pass to people through a bite.

The first three are usually combined into one injection. Rabies is given separately.

On international websites you will also read about vaccines against feline leukemia virus (FeLV), Chlamydia felis and Bordetella bronchiseptica. These are risk-based vaccines aimed mainly at multi-cat households, shelters and catteries, and they are not part of our vaccination protocol at Healthy Pet Hospital. The schedule we build for your cat rests on the core combination and rabies, the vaccines that protect against the diseases that actually threaten cats here.

The Kitten Vaccination Schedule, Step by Step

A new kitten vaccination schedule follows a clear pattern.

First core vaccine at 6 to 8 weeks. The exact start depends on the kitten's health, its environment and the mother's vaccination status. Kittens are born with antibodies from their mother's milk. These protect them early on, but they also block a vaccine from working if it is given too early. That is why the series does not start before 6 weeks.

Repeat doses every 2 to 4 weeks. The mother's antibodies fade at a different pace in every kitten, and nobody can see exactly when. Several doses, spaced 2 to 4 weeks apart, make sure at least one lands after the mother's protection has worn off and the kitten's own immunity can take over.

Final core dose at 16 weeks or older. The WSAVA Vaccination Guidelines, the global reference we follow at the clinic, recommend that the last dose of the kitten series be given at 16 weeks of age or later. In some kittens, leftover maternal antibodies can still block a dose given at 12 weeks, so stopping early leaves a gap.

Rabies from 12 weeks. Given as a separate injection, then repeated every year.

If a breeder or shelter started the vaccines before you took the kitten home, bring the record with you. We check which product was used and when, then continue from there rather than starting over. A kitten series that was begun but never finished is one of the most common gaps we find.

Not all vaccines are equal

This is a point I insist on with every kitten owner. Vaccine manufacturers do not all produce the same quality, and products differ in which strains of calicivirus and other viruses they cover. A vaccine also only works if it has been stored and handled at the right temperature the whole way from factory to syringe, in an unbroken cold chain. A poorly preserved vaccine looks identical in the vial and protects nothing. Where and how your kitten is vaccinated matters as much as the schedule itself.

What happens at each visit

Each vaccine visit is a full check-up, not just an injection. We take our time: we weigh the kitten, check the eyes, ears, mouth and skin, listen to the heart and lungs, feel the belly, and look for fleas, ear mites and signs of worms. Deworming usually happens at these same visits, which is why we put it on one calendar with the vaccines. You can read the full plan in our deworming schedule guide.

A Simple Cat Vaccination Schedule Table

Here is the cat shots timeline we follow at Healthy Pet Hospital. Treat it as the standard plan: your kitten's exact dates shift slightly depending on their age at the first visit.

If you already know the puppy vaccination schedule, the pattern will look familiar: a series of doses 2 to 4 weeks apart until 16 weeks, rabies from 12 weeks, then a booster every year.

Adult Cat Boosters: How Often Going Forward

About one year after the kitten series, your cat receives a booster. After that, the rule at our clinic is simple: every cat is vaccinated every year, for life, but we split the yearly vaccines into two separate consultations six months apart, rabies at one and the core vaccines at the other. Each vaccine is still given once a year, and your cat gets a full check-up every six months.

You may read on international websites that some cat vaccines can be spaced further apart. In Lebanon, we do not follow that approach. A yearly core booster and a yearly rabies booster, given six months apart, is the protocol we apply to every cat, and it is the schedule the clinic will map out for you.

If your adult cat has fallen behind, whether by a few months or a few years, there is no reason to feel stuck. Overdue cats should simply receive their booster now. In most cases one dose brings protection back, and we put the cat back on the six-month rhythm from that date.

Each of these two vaccine visits is also a full wellness exam. Cats hide illness well, and many of the problems we catch early, from dental disease to kidney changes in older cats, are found at these routine appointments. For most cats, one check-up a year is not enough: seeing your cat every six months lets us find disease earlier, and gives you a regular moment to discuss any problem with us.

Indoor Cats Still Need Vaccines

This is the most common question we get about cat vaccines, and the honest answer is yes: an indoor cat vaccination schedule still includes the core vaccines, rabies included.

Panleukopenia virus is very tough and survives a long time in the environment, so it can come into your home on shoes or clothes without your cat ever stepping outside. A single escape through an open door or balcony is enough to meet a sick stray. A new kitten, a visiting pet, or a stay at a boarding facility can all bring exposure. And rabies carries legal and public health weight: an unvaccinated cat that bites someone, even at home, creates a problem that a yearly injection would have prevented.

Indoor life lowers your cat's risk. It does not remove it. What does not change for an indoor cat is the protocol itself: the core vaccines and rabies, each once a year at visits six months apart, the same as for any other cat. What these visits adjust is everything around it, from parasite control to weight and dental health, based on how your cat actually lives.

Dr Chadi's Take: Vaccinate on Health, Not Just the Calendar

In my experience, the best cat vaccination schedule is the one built for the cat in front of me, not copied from a poster. Two kittens of the same age can arrive at different starting points: one healthy, from a vaccinated mother and a clean home, the other from an unknown background. The core vaccines and the annual rhythm are the same for both. When the series starts, and the product used and how it was stored, are where the real decisions sit.

At our clinic we see the consequences of both extremes. We see kittens who received a vaccine of unknown origin and still fell ill with panleukopenia, and we see adult cats who were never boosted because someone assumed indoor cats do not need it. Our approach is to vaccinate where it protects, skip what the cat genuinely does not need, and never skip the full exam that comes with each visit. A kitten that is unwell on vaccine day is treated first and vaccinated once recovered.

Nutrition belongs in the same conversation, which is why we cover feeding at the first visit.

Questions Cat Owners Always Ask

What vaccines does my kitten need and at what age?

Kittens need the core vaccine against panleukopenia, herpesvirus and calicivirus, starting at 6 to 8 weeks, the exact start depending on the kitten's health, environment and the mother's vaccination status, and repeated every 2 to 4 weeks until at least 16 weeks of age, usually three doses in total. Rabies is given from 12 weeks. After the kitten series, boosters are annual for life.

Does an indoor cat really need to be vaccinated?

Yes. Indoor cats still need the core vaccines, including rabies, because viruses like panleukopenia can be carried into the home on shoes and clothes, and escapes, new pets and vet or boarding stays all create exposure. Indoor living lowers the risk but does not remove it.

How often does my adult cat need booster shots?

At Healthy Pet Hospital, adult cats receive a booster about one year after the kitten series and then every year for life, with the core vaccines and rabies given at two separate visits six months apart. Each vaccine stays yearly, your cat is checked every six months, and it is the protocol we follow for every cat in Lebanon.

Is the rabies shot required for cats in Lebanon?

Rabies is a core vaccine for every cat, indoor or outdoor, because the disease is fatal and can pass to people. At our clinic the rabies vaccine is first given from 12 weeks of age and then repeated every year, at its own visit six months after the core booster. An up-to-date rabies record is also needed for travel.

My kitten missed a booster, do we start over?

Usually not. If a dose is late, we give it as soon as possible and continue the series from there, making sure the final core dose still lands at 16 weeks or older. If the gap was very long, we may add a dose, so call us with your kitten's dates and we will tell you exactly what is needed.

What side effects are normal after a cat vaccine?

Mild tiredness, a smaller appetite, or slight soreness at the injection site for a day or two are normal and pass on their own. Repeated vomiting, facial swelling, hives or trouble breathing are not normal. If you see any of those, call us right away on +961 3 517 831, the emergency line answers 24/7.
