A printable planner: track your kitten's weight from birth to 12 months, and walk into every vet visit with the right questions and paperwork already sorted.
Kittens grow fast and predictably for the first several months, which makes weight one of the simplest ways to check that things are on track. A handy rule of thumb: a kitten's weight in pounds roughly matches its age in months, up until about 4-5 months old. Weigh your kitten weekly for the first two months, then every 2-4 weeks after that, and jot the number in the log below.
| Age | Typical Weight | What's Happening |
|---|---|---|
| Birth | 3-4 oz (85-113 g) | Eyes closed, fully dependent on mom |
| 1 week | 6-8 oz (170-230 g) | Birth weight roughly doubles |
| 2 weeks | 7-10 oz (200-280 g) | Eyes open, starting to hear |
| 4 weeks (1 mo) | ~1 lb (450 g) | Walking steadily, weaning begins |
| 8 weeks (2 mo) | ~2 lb (900 g) | Fully weaned, first vet visit range |
| 12 weeks (3 mo) | ~3-3.5 lb (1.4-1.6 kg) | Vaccine series in progress |
| 4 months | ~4 lb (1.8 kg) | Adult teeth coming in |
| 6 months | ~5.5-6.5 lb (2.5-3 kg) | ~75% of adult size; spay/neuter window |
| 8 months | ~7-8 lb (3.2-3.6 kg) | Growth rate slowing |
| 10-12 months | 7.5-10 lb females / 8-12 lb males | Near or at adult weight |
Weights vary by breed. Large breeds like Maine Coons grow more slowly and can keep filling out until 18-24 months, while smaller breeds mature faster. Use this chart as a general guide, not a diagnosis.
| Date | Age | Weight | Notes |
|---|---|---|---|
Most kittens need a first exam around 6-8 weeks old, then follow-up visits every 3-4 weeks until roughly 16 weeks to finish the core vaccine series. Print this list and check items off before each appointment.
Timing follows the 2020 AAHA/AAFP Feline Vaccination Guidelines. Your vet may adjust this based on your kitten's health, lifestyle, and local disease risk.
| Age | Typical Care |
|---|---|
| 6-8 weeks | First exam, FVRCP #1, deworming, fecal parasite check |
| 9-11 weeks | FVRCP #2, FeLV #1, deworming |
| 12-14 weeks | FVRCP #3, FeLV #2 |
| 16 weeks | FVRCP #4 (final core dose), rabies |
| 4-6 months | Spay or neuter (AVMA Fix by Five recommends by 5 months) |
| 12 months | Adult wellness exam; transition to adult food and adult vaccine schedule |
FVRCP protects against feline herpesvirus, calicivirus, and panleukopenia. FeLV (feline leukemia) is treated as core for kittens under 1 year by most practices, indoor or outdoor. Rabies requirements vary by state, check your local laws.
Pair this planner with a personalized feeding schedule based on your kitten's current weight and age.
🐾 Use the Kitten Feeding CalculatorAs a rough rule of thumb, a kitten's weight in pounds roughly matches its age in months up to about 4-5 months old. Growth slows after 4-6 months, and most kittens reach adult weight by 10-12 months.
Typically a first visit at 6-8 weeks, then boosters every 3-4 weeks until about 16 weeks, followed by a spay/neuter visit around 4-6 months and an adult wellness exam at 12 months.
The AVMA-endorsed Feline Fix by Five initiative recommends spaying or neutering by 5 months of age, since kittens can become pregnant as early as 4 months old.
This planner is educational and not a substitute for veterinary advice. Always confirm vaccine timing, weight targets, and spay/neuter scheduling with your veterinarian, especially for rescue, orphaned, or unwell kittens.
