📈Kitten Growth Chart by Age

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.

AgeTypical WeightWhat's Happening
Birth3-4 oz (85-113 g)Eyes closed, fully dependent on mom
1 week6-8 oz (170-230 g)Birth weight roughly doubles
2 weeks7-10 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 months7.5-10 lb females / 8-12 lb malesNear 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.

When to call the vet: No weight gain for 2+ days in a kitten under 8 weeks, or any kitten that is consistently underweight for its age, warrants a call. Slow or stalled weight gain is often the earliest sign of parasites, illness, or an underlying feeding problem.

💉Kitten Vaccine & Care Schedule

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.

AgeTypical Care
6-8 weeksFirst exam, FVRCP #1, deworming, fecal parasite check
9-11 weeksFVRCP #2, FeLV #1, deworming
12-14 weeksFVRCP #3, FeLV #2
16 weeksFVRCP #4 (final core dose), rabies
4-6 monthsSpay or neuter (AVMA Fix by Five recommends by 5 months)
12 monthsAdult 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.

Frequently Asked Questions

How much should a kitten weigh at each age?

As 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.

How often does a kitten need vet visits in the first year?

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.

When should a kitten be spayed or neutered?

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.
