Cat calories by weight
How many calories should a 4 kg cat eat?
A 4 kg cat (8.82 lb) is the example worked through on the PetKira feeding calculator page, and it is a good one to start from: the numbers below show how neutering, activity, age and a weight-loss goal each change the daily calories.
The short answer
A 4 kg neutered adult cat needs about 238 kcal a day (277 if intact). Starting point, not veterinary advice.
In pounds, 4 kg (8.82 lb). Fed as 2 meals, that is about 119 kcal per meal for a neutered or spayed adult (about 139 kcal if intact). Starting point, not veterinary advice.

Two meals is common feeding practice for adults, not a published calorie standard. Ask your vet how often to feed your pet.
What a 4 kg cat looks like
Four kilograms is about four 1-litre bottles of water, a weight many adult domestic cats sit near, though a healthy weight depends on frame size and body condition more than on the scale alone.
Neutering lowers energy needs in the engine's factors: a 4 kg intact cat is estimated at 277 kcal a day against 238 kcal for a neutered or spayed cat at moderate activity. Indoor, low-activity cats are lower again at 198 kcal, which is also the weight-loss figure. Starting point, not veterinary advice.
How much food is that? A worked example
As an example only, with a dry cat food with 370 kcal per 100 g, 238 kcal a day for a neutered or spayed adult is 64 g a day, or 32 g in each of 2 meals. Your food will have a different energy value, so read your own label. Starting point, not veterinary advice.
Cats often do well with several small meals. Two is common practice and three works for many households, at about 79 kcal each from a 238 kcal day. Meal counts are not part of a published calorie standard, so ask your vet what suits your cat. Starting point, not veterinary advice.
If you feed both wet and dry food, count both. Decide how many calories the wet meal provides from its label, subtract that from the daily number, and feed the rest as dry food.
Day-to-day feeding at 4 kg
In a home with more than one cat it is easy for a 4 kg cat to eat another cat's share. Feed in separate rooms or at separate spots, take the bowls up after the meal, and work out each cat's figure from its own weight and life stage: a 4 kg neutered or spayed adult is 238 kcal a day, and a heavier or lighter cat next door will be different (the 3 kg and 5 kg cat pages show how much). Treat each cat as its own plan, not as half of a shared one. Starting point, not veterinary advice.
4 kg in pounds
4 kg (8.82 lb). The calculator takes pounds as well and converts them exactly (1 lb is 0.45359237 kg) before it calculates. For example, 9 lb is 4.08 kg, which gives 241 kcal a day for a neutered or spayed adult cat at moderate activity. Starting point, not veterinary advice.
How 4 kg compares with nearby weights
- Heavier: a 5 kg cat needs 43 kcal more a day than a 4 kg cat (281 versus 238 for a neutered or spayed adult at moderate activity), which is 18% more energy for 25% more body weight. Starting point, not veterinary advice. See the 5 kg cat page.
- Lighter: a 3 kg cat needs 47 kcal less a day than a 4 kg cat (191 versus 238 for a neutered or spayed adult at moderate activity), which is 20% less energy for 25% less body weight. Starting point, not veterinary advice. See the 3 kg cat page.

Got questions?
4 kg cat calories: questions
How many calories should a 4 kg cat eat per day?
A 4 kg neutered or spayed adult cat at moderate activity needs about 238 kcal a day, and an intact adult about 277 kcal. At low activity the neutered figure is 198 kcal. A weight-loss goal for an adult uses the resting energy of the current weight, 198 kcal. Starting point, not veterinary advice.
How much food does a 4 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 dry cat food with 370 kcal per 100 g would mean 64 g a day (32 g per meal over 2 meals) to supply the 238 kcal that a neutered or spayed adult cat of 4 kg needs at moderate activity. Measure by weight if you can. Starting point, not veterinary advice.
How many calories does a 4 kg cat need to lose weight?
For an adult cat the weight-loss goal is the resting energy of the current weight: 198 kcal a day at 4 kg. That is also the low-activity figure, so a low-activity cat is already at the lowest safe estimate and should ask the vet before going further. Weight loss in cats should be gradual and supervised. Starting point, not veterinary advice.
How much wet food does a 4 kg cat need?
It depends on the food's calories, which vary a lot between brands, so read the label. As an example only, a wet food with 85 kcal per 100 g would be about 280 g a day to supply 238 kcal for a neutered adult. Mixed wet and dry feeding should add up to the same daily total. Starting point, not veterinary advice.
