A vaccine record needs 3 date fields per row and nothing else: the date given, the date next due, and the date the reminder fires, set 30 days before the due date. Adult core vaccines then run on a 3-year cycle, so 1 filled row covers 2026 to 2029. The whole page fits 7 rows, takes 10 minutes to build from old clinic printouts, and answers the 2 questions that come up at a boarding desk and at 23:00 before a flight.
Three dates, because one date is not a record
A single date tells you the cat was vaccinated. It does not tell you when the protection is expected to lapse, and it does not tell you when to book. The 3 fields split those jobs. Date given is history and belongs to the clinic. Next due is the deadline and belongs on the page. Reminder date is the action, and 30 days is the right lead time for a non-urgent booster: long enough to book a slot, short enough that you do not forget between the reminder and the visit. Add a 7-day second reminder and the miss rate drops further.
The record page, filled in as an example
| Vaccine | Date given | Next due | Reminder | Interval (months) |
|---|---|---|---|---|
| FVRCP dose 1 | 2024-05-04 | 2024-06-01 | 2024-05-25 | 4 |
| FVRCP dose 2 | 2024-06-01 | 2024-06-29 | 2024-06-22 | 4 |
| FVRCP dose 3, 16 weeks | 2024-06-29 | 2025-06-29 | 2025-05-30 | 12 |
| Rabies, first | 2024-06-29 | 2025-06-29 | 2025-05-30 | 12 |
| Rabies, 3-year product | 2025-06-29 | 2028-06-29 | 2028-05-30 | 36 |
| FVRCP adult booster | 2025-06-29 | 2028-06-29 | 2028-05-30 | 36 |
| FeLV, outdoor access | 2025-06-29 | 2026-06-29 | 2026-05-30 | 12 |
Every row carries the same 5 cells, and the last cell is what makes the 3-year cycle visible: 4, 4, 12, 36. The kitten series compresses into 8 weeks, then 1 year, then 3 years. Nothing on the page needs a dose or a volume; the clinic label covers that, and copying it by hand introduces errors that no one catches later.
What the 3-year cycle actually covers
For adult cats, the core vaccines are FVRCP (herpesvirus, calicivirus, panleukopenia) and rabies. Many clinics revaccinate an adult indoor cat every 3 years for both, following the product label and local law, and a 1-year product still requires 12 months. The distinction matters: the interval is set by the label on the vial and by the rabies regulation where you live, not by a preference. FeLV is not core for a cat that never goes outside, and where it is used the interval is usually 12 months. Bordetella and Chlamydia are situation-specific and commonly 12 months for boarding or multi-cat homes.
Kitten math: 3 doses, 16 weeks, then 12 months
Antibodies from the mother block a vaccine for a variable number of weeks, which is why kittens get repeated doses. A common schedule is 3 doses at 8, 12 and 16 weeks, with the final dose at or after 16 weeks, then a booster at 12 months, then the 3-year interval. Rows 1 to 3 in the table above show the pattern: 4 weeks, 4 weeks, 12 months. A kitten vaccinated only twice, or finishing at 12 weeks, is the case where the record page earns its place, because the gap is visible on 1 line instead of buried in 3 printouts.
The fields a clinic will ask for and owners skip
Six items belong beside the 3 dates: product name, lot or serial number, injection site, clinic name, vet signature or stamp, and any reaction within 48 hours. The lot number is the one people drop, and it is the only way to trace a batch when a reaction turns up across a run of doses. The site (left shoulder, right shoulder, hind limb) matters because a lump at an injection site that persists past 3 months needs a look. Record a reaction as 1 line with a time: facial swelling at 20 minutes, vomiting at 2 hours, lethargy for 24 hours.
Proof for boarding, grooming and travel
Boarding kennels and groomers usually want rabies proof that is current, and many ask for FVRCP within 1 to 3 years. A phone photo of the record page is accepted by most, but a printed copy with the clinic stamp settles arguments. For travel, the rabies rules change by destination: the EU and UK generally require a microchip before the rabies vaccine, a wait of 21 days after the vaccine, and a titer test 3 months before entry for some routes. Those are 3 different dates, and all 3 belong on the same page, in the margin under the rabies row.
Reminders that survive a phone change
Set the 30-day reminder in 2 places, a calendar app and a paper year planner, and set a 7-day follow-up. Clinic reminder systems fail silently when an email changes or a number is recycled, so treat the clinic text as a backup rather than the plan. Do a 12-month audit in the same week every year: open the page, check every row, and rewrite any due date that has already passed. The audit takes 4 minutes and catches the 1 row that a move or a clinic switch left behind.
Running late, and what to do about it
A booster that is 2 to 6 weeks late is a common situation, and for an adult cat on a 3-year core vaccine most clinics will simply give the dose and reset the interval; a kitten mid-series needs the series restarted rather than stretched. Rabies is stricter, since the legal status of a lapse depends on local rules and can affect a boarding booking or a border crossing. If the record shows a gap longer than 12 months, call before you book, and write the answer on the page: 1 line now saves the same conversation in 3 years.
Build the page in 5 steps
- Take 1 photo of every old vaccine certificate and read the dates off the photo, not from memory.
- Write 1 row per dose with the 5 cells above, in date order.
- Add 2 reminders per future row: 30 days before and 7 days before.
- Staple the clinic printout behind the page, since a stamp beats handwriting at a boarding desk.
- Set a 12-month audit and store a photo of the finished page in the health folder.
The page is only 7 rows, and it replaces a shoebox of certificates that nobody can read at the counter. Fill it once, keep the 3 dates current, and the 3-year cycle stops being a surprise.

Frequently asked
Is a 3-year rabies vaccine the same as a 3-year FVRCP?
No. Each product carries its own licensed duration, and rabies duration is also set by local law, so a 1-year rabies product still needs an annual dose even if the FVRCP row says 36 months. Read the label on the vial, not the interval you remember from a previous cat, and write both intervals on the record page.
Do I need to keep the paper certificate if I have a photo?
Keep both for at least 3 years. A photo settles most questions at a grooming or boarding desk, but a stamped printout is what a border officer or an insurance claim may ask for, and old clinic systems get retired. Scan the certificate at 300 dpi into the health folder and keep the original in the same envelope as the record page.
My cat is 12 and indoors. Can I stop boosters?
That is a conversation, not a default. Many clinics continue core vaccines on a 3-year cycle for healthy older cats because the risk of a reaction is low and the disease risk is not zero, while others shorten or skip based on exam findings and blood work. Rabies is usually the one that stays mandatory, because it is a legal requirement in many places.
