Many cat owners only think about "How often should cats be vaccinated?" when it's time for boarding, moving, or their vet reminds them. In reality, vaccines aren't just for paperwork; they help protect cats from several highly contagious and high-risk diseases. Cats are particularly good at hiding illness, so by the time they show lethargy or decreased appetite, it's often more than just a mild cold.

This article provides a vaccination schedule from a daily care perspective for kittens, adult cats, and before boarding. Actual vaccination should always be determined by a veterinarian based on the cat's age, health status, living environment, and vaccination history. If your cat has been sick recently, is on medication, or has had an adverse reaction to a vaccine in the past, be sure to inform your vet.

Key takeaways

• Kitten vaccinations typically start with the first dose around 8 weeks of age, with boosters scheduled every few weeks as recommended by your veterinarian until basic immunity is established.
• Common core cat vaccines in Taiwan primarily protect against feline distemper, feline herpesvirus, and feline calicivirus. Even indoor-only cats can be at risk of infection through shoes, travel carriers, or visits to the vet.
• It's not recommended to vaccinate your cat the day before boarding. Confirm the facility's requirements in advance and allow time for the body to build immunity and reduce stress.
• If your cat experiences unusual reactions after vaccination, such as facial swelling, difficulty breathing, persistent vomiting, severe weakness, or unsteadiness, contact your animal hospital immediately.

What Do Cat Vaccinations Primarily Prevent?

Common core vaccines for cats in Taiwan primarily protect against diseases like feline panleukopenia (feline distemper), feline herpesvirus, and feline calicivirus. These diseases can spread through secretions, environmental contact, or contact with other cats. Kittens, cats with weakened immune systems, and multi-cat households need to be particularly vigilant.

Some owners believe that indoor-only cats don't need vaccinations. However, risks can still arise from shoe soles, outdoor gear, veterinary visits, or even brief contact with other cats. While indoor living reduces the chance of infection, it doesn't eliminate the risk entirely.

Kitten Vaccination Schedule: Usually Starts Around 8 Weeks Old

A kitten's immune system is still developing. The first dose is typically administered around 8 weeks of age, followed by booster shots every few weeks as recommended by the veterinarian until basic immunization is complete. The specific vaccine brands and protocols may vary slightly between clinics, so don't rely solely on online schedules.

• Step 1: Have your veterinarian confirm the kitten's age, weight, general condition, appetite, and parasite status.
• Step 2: Schedule the first dose and subsequent booster appointments according to recommendations.
• Step 3: Before completing the basic immunization series, avoid contact with unknown cats or shared items.

If you've adopted a kitten, try to obtain vaccination records from the rescue organization, shelter, or previous owner. If records are unavailable, it doesn't necessarily mean all vaccinations need to be repeated, but your vet will need to re-evaluate to ensure adequate protection and appropriate vaccination intervals.

How Often Do Adult Cats Need Vaccinations? Depends on Risk and History

After completing the initial vaccination series, adult cats typically receive regular booster shots. The frequency depends on the type of vaccine, age, health status, and lifestyle. Multi-cat households, cats that go outdoors, frequent boarders, or those who have had contact with stray cats generally face higher risks than single cats living indoors.

The most practical approach is to photograph or save your cat's vaccination booklet or past receipts and present them to your veterinarian during each check-up. Don't just rely on remembering "I think it was last year"; vague dates can cause problems when boarding, traveling abroad, or seeking emergency care.

Before Boarding: Don't Wait Until the Day Before to Boost

If you're planning to board your cat, it's advisable to check the boarding facility's vaccination requirements in advance. Some places require core vaccinations to be up-to-date, with a specific number of days passed since the last vaccination to allow the body to develop immunity. Getting a vaccination the day before boarding is generally not ideal and can add stress to your cat before a new environment.

Check These 4 Things Before Boarding

• Are the vaccination records complete and the dates clear?
• Has the cat been sneezing, having diarrhea, losing appetite, or showing lethargy recently?
• Do you also need to schedule parasite treatment, nail trimming, or basic grooming?
• Can the boarding environment minimize stress, such as providing a private space, managing scents, and maintaining care records?

What Reactions Should Be Observed After Vaccination?

Shortly after vaccination, your cat might be sleepier, have a slightly reduced appetite, or show some sensitivity at the injection site. Usually, quiet observation is sufficient. Avoid bathing, long-distance travel, or other high-stress activities on the day of vaccination.

However, if you notice facial swelling, difficulty breathing, persistent vomiting, severe weakness, unsteadiness, or a significant decline in appetite and energy, do not wait. Contact your veterinary hospital immediately. If your cat has had a previous vaccine reaction, be sure to remind your veterinarian before the next vaccination.

Which Cats Should Consult a Vet First Before Vaccination?

Not every cat is suitable for vaccination on the same day. Cats that have recently moved, are experiencing high stress, have a fever, diarrhea, vomiting, unstable chronic conditions, or have recently undergone surgery should be evaluated by a veterinarian first. Senior cats can still be vaccinated, but their overall health status, lifestyle risks, and the necessity of the vaccine need careful consideration.

Frequently Asked Questions (FAQ)

Do indoor cats that never go outside still need vaccinations?

In most cases, it's still recommended to discuss core vaccines with your veterinarian. Indoor cats have lower risks, but contact can still occur through people, objects, veterinary visits, or temporary boarding.

Can cat vaccinations be scheduled on the same day as bathing?

This is generally not recommended. Both vaccination and bathing can be stressful. It's best to schedule them separately, allowing your cat to rest and be observed quietly after vaccination.

I forgot to get a booster shot for a long time. Do I need to start over?

Not necessarily. Bring your vaccination records to your veterinarian for assessment. The vet will determine the best way to proceed based on the interval, age, and risks.

How long after vaccination can a cat be boarded?

This varies by boarding facility, but it's usually recommended to confirm requirements several weeks in advance. Avoid getting a booster shot the day before check-in, as both immunity and the cat's condition may not be optimal.
