Kitten Vaccine Schedule by Week

A kitten's first vaccines come as a series spread over several weeks, and it is easy to lose track of which shot is due when. PetHealthLog lets you lay the schedule out week by week, tick off each vaccine and booster as it is given, see what is coming next, and walk into the vet with a clear record - free, with no account, and it works offline.

The kitten shot series is easy to lose track of

Kitten vaccination is not a single appointment. It is a series of shots given a few weeks apart over the first months of life, and the spacing is the whole point - a young kitten still carries fading antibodies from its mother, so protection is built up across several visits rather than all at once. That makes the schedule genuinely useful to follow, and genuinely easy to muddle.

Between settling a new kitten in, work, and everything else, "I think the next one is in a couple of weeks" is how a booster ends up late. And a late or skipped booster can leave a gap in the very protection the series is meant to provide.

A by-week view turns that into something you can actually see. PetHealthLog keeps it simple: it is free, asks for no account, and works offline, so the schedule and the record of what has been done live in one place you can open anywhere - including the vet's waiting room.

A typical kitten vaccine timeline, week by week

A general picture of how the early shots are usually spaced. It is a guide for laying out your own schedule - your veterinarian sets the exact weeks and which vaccines are included for your kitten and region.

AgeRoughly what tends to happen
6 to 8 weeksFirst core kitten vaccinations usually begin around this age, the start of the series.
9 to 12 weeksA booster is commonly given a few weeks after the first, continuing the series.
13 to 16 weeksA further booster around this age often completes the initial kitten series.
From here onLater boosters follow on a schedule your vet sets, often around a year and then periodically.

PetHealthLog does not pick these dates for you. You enter the schedule your vet gives you and mark each shot done as it happens, so the by-week plan and the real record stay together.

What the kitten vaccine tracker actually does

A schedule only helps if it tells you what is next and remembers what is done. Here is how PetHealthLog handles both.

Why "free, offline, no account" matters here

Bringing home a new kitten is busy enough without a login screen between you and a quick note that this morning's shot is done. You might want to check what is due next while you are still at the clinic, where the signal can be weak, or jot something down the moment you get home.

PetHealthLog stores everything locally on your device. There is no account to create, nothing is uploaded to a server, and there is no tracking. It opens instantly, lets you mark a shot done or check the schedule whether or not you are online, and keeps the data yours. You can export a backup any time and restore it on another phone.

Frequently asked questions

When do kittens usually start their vaccines?
Kitten vaccination typically begins at around six to eight weeks of age and continues as a series of boosters every few weeks until roughly sixteen weeks, because the protection from a single shot is not enough on its own. The exact weeks and which vaccines are included depend on your kitten and your region, so the schedule your veterinarian sets is the one to follow. PetHealthLog lets you record that schedule and tick off each shot as it is given.
Why does a kitten need several shots instead of one?
A young kitten carries antibodies from its mother that fade over the first weeks of life, and those antibodies can blunt a single vaccine. A series given a few weeks apart is designed to provide protection as the borrowed immunity wears off, which is why the by-week spacing matters and why missing or bunching up the boosters can leave a gap. Your vet decides the specific weeks; the tracker just helps you keep to them.
Is this kitten vaccine tracker really free?
Yes. Setting up the schedule, marking each vaccine and booster done, seeing what is due next, tracking weight and deworming, and the PDF report are all free to use. There is no sign-up and no account, and your kitten's records stay on your own device.
What happens if I miss a booster?
A shot you have not marked done stays visible instead of quietly disappearing, so a missed or overdue booster is something you notice rather than realise weeks later. If a booster is late, contact your veterinarian, since the right way to get back on schedule depends on how much time has passed and which vaccine it is.
Does it work without an internet connection?
Yes. PetHealthLog is a progressive web app that works offline. Once it has loaded you can mark a shot done or check what is coming next without a connection, which is handy in a waiting room or anywhere the signal is poor.
Can I track more than one kitten?
Yes. You can keep a separate profile for each pet, so two kittens from the same litter, or a kitten and an older cat, each get their own schedule and record without anything getting mixed up.
Is this a substitute for veterinary advice?
No. PetHealthLog is a record-keeping tool, not veterinary advice. Which vaccines your kitten needs and exactly when they are due should always be decided by a licensed veterinarian, who will tailor the schedule to your kitten's age, health and where you live.
