Cat calories by weight
How many calories should a 3 kg cat eat?
A 3 kg cat (6.61 lb) is small for an adult and about right for a growing kitten, so the first thing to settle is life stage. This page gives the daily calories for a 3 kg cat as a kitten, an adult and a senior, at every activity level.
The short answer
A 3 kg neutered adult cat needs about 191 kcal a day (223 if intact). Starting point, not veterinary advice.
In pounds, 3 kg (6.61 lb). Fed as 2 meals, that is about 96 kcal per meal for a neutered or spayed adult (about 112 kcal if intact). Starting point, not veterinary advice.
Not veterinary advice. These figures are general estimates for healthy dogs and cats. They do not diagnose, treat or replace the advice of a licensed veterinarian. Pets with medical conditions, pregnant or nursing pets, and pets that are underweight or overweight should have their calorie targets set by a vet. If your pet's weight or appetite changes, talk to your veterinarian. See also our AI disclaimer.

Two meals is common feeding practice for adults, not a published calorie standard. Ask your vet how often to feed your pet.
What a 3 kg cat looks like
Three kilograms is about three 1-litre bottles of water. A small-framed adult cat can sit near this weight, and a kitten passes through it as it grows. Kittens use a higher growth factor, so a 3 kg kitten is estimated at 399 kcal a day, against 191 kcal for a 3 kg neutered or spayed adult. Which row applies depends on age, not weight. Starting point, not veterinary advice.
If you are unsure whether 3 kg is a healthy weight for your adult cat, ask your vet. Frame size matters, and an unexplained drop in weight in an adult cat is worth a call to the clinic.
How much food is that? A worked example
As an example only, with a wet cat food with 85 kcal per 100 g, 191 kcal a day for a neutered or spayed adult is 225 g a day, or 112 g in each of 2 meals. Your food will have a different energy value, so read your own label. Starting point, not veterinary advice.
Small cats eat very little at a time. Split across two meals, a neutered adult's day is about 96 kcal each, and some cats prefer three smaller meals at about 64 kcal each (common practice, not a published standard; ask your vet). Starting point, not veterinary advice.
Wet food is a convenient way to give small, measured portions. Check the label for kcal per can, pouch or 100 g and count it toward the total, including any dry food you also feed.
Day-to-day feeding at 3 kg
Many small cats graze from a bowl that is always full. If you want to move to measured meals, weigh what a normal day of grazing really is for a week, compare it with the figure here (191 kcal for a neutered or spayed adult, 399 kcal for a kitten), then split the target into the number of meals you can keep up. Move the times a little at a time rather than all at once, and ask your vet before changing a kitten's routine. Starting point, not veterinary advice.
3 kg in pounds
3 kg (6.61 lb). The calculator takes pounds as well and converts them exactly (1 lb is 0.45359237 kg) before it calculates. For example, 7 lb is 3.18 kg, which gives 200 kcal a day for a neutered or spayed adult cat at moderate activity. Starting point, not veterinary advice.
How 3 kg compares with nearby weights
- Heavier: a 4 kg cat needs 47 kcal more a day than a 3 kg cat (238 versus 191 for a neutered or spayed adult at moderate activity), which is 25% more energy for 33% more body weight. Starting point, not veterinary advice. See the 4 kg cat page.

Got questions?
3 kg cat calories: questions
How many calories should a 3 kg cat eat per day?
A 3 kg neutered or spayed adult cat at moderate activity needs about 191 kcal a day, and an intact adult about 223 kcal. At low activity the neutered figure is 160 kcal. A weight-loss goal for an adult uses the resting energy of the current weight, 160 kcal. Starting point, not veterinary advice.
How much food does a 3 kg cat need each day?
It depends on how many calories the food has, so use the label on your own food. For comparison, a wet cat food with 85 kcal per 100 g would mean 225 g a day (112 g per meal over 2 meals) to supply the 191 kcal that a neutered or spayed adult cat of 3 kg needs at moderate activity. Measure by weight if you can. Starting point, not veterinary advice.
Is a 3 kg cat underweight?
Not necessarily. Healthy weight depends on frame, age and body condition, and small-framed adult cats can be a healthy 3 kg. A kitten is expected to be light. If you can see or feel the ribs and spine very easily, or your adult cat has lost weight without a reason, ask your vet.
How many calories does a 3 kg kitten need?
The engine gives a kitten (under 1 year) a growth factor, so a 3 kg kitten is estimated at 399 kcal a day, whatever the activity level. Kittens grow quickly, so weigh them often and re-check the number as they gain weight; your vet can check growth. Starting point, not veterinary advice.
