Welcoming a British Shorthair kitten into your home is a heartwarming experience, but protecting their health begins with the right vaccination plan. As experienced breeders, we prioritize early medical care to ensure our kittens grow into strong, resilient adults. Vaccinations play a vital role in building immunity and preventing potentially deadly diseases. This detailed guide outlines the complete vaccination schedule for British Shorthair kittens, including what each vaccine does, when to administer them, associated costs, and common questions from pet parents.
Why Vaccinations Matter for British Shorthair Kittens
British Shorthair kittens may be sturdy by nature, but they still face risks during their early weeks. Vaccines shield them from serious infections and prepare them for a healthy future. As breeders, we start vaccinations at the appropriate age to give our kittens the best possible start. Vaccines:
- Prevent the spread of fatal illnesses like feline panleukopenia and rabies
- Strengthen your kitten’s immune system during development
- Protect against diseases transmitted by other cats
- Meet legal requirements for pet ownership and travel
Furthermore, following a consistent vaccine schedule builds your kitten’s resistance before they face the outside world.

Core and Non-Core Vaccines in the British Shorthair Kitten Vaccination Schedule
What Are Core Vaccines?
Core vaccines are essential for all British Shorthair kittens, regardless of their lifestyle. We never skip these, even for indoor-only kittens. These vaccines include:
- Feline Panleukopenia (FPV): A highly contagious virus that targets the immune system and can be fatal.
- Feline Herpesvirus (FHV-1): Leads to feline viral rhinotracheitis, which causes severe respiratory issues.
- Feline Calicivirus (FCV): Triggers painful mouth ulcers and respiratory symptoms.
- Rabies: A deadly virus that spreads to humans; most regions legally require this vaccine.
What Are Non-Core Vaccines?
We base non-core vaccines on each kitten’s environment and future lifestyle. If a kitten is going to live with other cats or explore outdoors, we often recommend:
- Feline Leukemia Virus (FeLV): Protects against a contagious and incurable virus.
- Chlamydia felis: Prevents conjunctivitis caused by this bacterial infection.
- Bordetella bronchiseptica: Important for kittens in shelters or catteries.
Naturally, we discuss each option with new owners before sending kittens home.
British Shorthair Kitten Vaccination Timeline
We follow a structured kitten vaccination schedule that ensures timely immunity development. Here’s how we vaccinate our kittens before adoption:
6–8 Weeks Old
- FVRCP Vaccine (includes FPV, FHV-1, FCV)—First dose
- Deworming — We begin this if not already been done by the time of adoption
10–12 Weeks Old
- FVRCP Booster — Second dose
- FeLV Vaccine — First dose for at-risk kittens
- Continued deworming — We recommend staying on schedule
14–16 Weeks Old
- FVRCP Booster — Final dose of the initial series
- FeLV Booster — If applicable, we administer the second dose
- Rabies Vaccine — Typically given once the kitten is at least 12 weeks old
6 Months – 1 Year
- FVRCP Booster — One-year booster
- Rabies Booster — Depending on your local regulations
- FeLV Booster — If your cat’s lifestyle justifies it
Altogether, this vaccination routine ensures your British Shorthair develops robust immunity.

Adult British Shorthair Vaccination Schedule
Even as adults, British Shorthairs require booster vaccines to maintain protection. After the initial kitten series, we advise the following:
- FVRCP — Every 1 to 3 years
- Rabies — Yearly or every 3 years, based on your regional laws
- FeLV — Annually, but only if your cat goes outdoors or lives with other cats
To stay safe, we recommend annual vet checkups along with vaccination updates.
Cost of Vaccinations for British Shorthair Kittens
We’re often asked about the cost of vaccines. While prices can vary by location, here’s a rough guide for planning:
- FVRCP series (3 doses): $60–$90 total
- FeLV series (2 doses): $40–$60 total
- Rabies vaccine: $20–$30
- Deworming: $10–$25 per dose

Some clinics offer kitten wellness packages, which cover exams, vaccinations, and deworming for $150–$300. These often provide excellent value. Additionally, many pet insurance plans include wellness add-ons to help cover routine vaccinations.
What to Expect on British Shorthair Kitten Vaccination Day
As breeders, we always prepare our kittens for a calm vet experience. You can do the same by:
- Bringing a soft carrier lined with familiar bedding
- Scheduling morning appointments to avoid long waits
- Offering a treat and plenty of praise afterward
- Keeping your kitten indoors and calm for a day or two
Typically, kittens bounce back quickly from vaccinations. However, rest helps reduce stress.
Possible Side Effects of Vaccines in British Shorthair Kittens
British Shorthairs usually handle vaccines well. Still, mild side effects may occur:
- Lethargy
- Slight swelling at the injection site
- Low-grade fever
- Temporary loss of appetite
Side effects should resolve within 48 hours. If your kitten seems distressed or shows signs like vomiting or facial swelling, contact your vet immediately.
