Cat calories by weight

How many calories should a 6 kg cat eat?

At 6 kg (13.23 lb), a cat is either large-framed or heavier than many adult cats, and your vet is the right person to say which. This page shows what the engine estimates for a 6 kg cat at each life stage and activity level, plus the adult weight-loss starting figure.

The short answer

A 6 kg neutered adult cat needs about 322 kcal a day (376 if intact). Starting point, not veterinary advice.

In pounds, 6 kg (13.23 lb). Fed as 2 meals, that is about 161 kcal per meal for a neutered or spayed adult (about 188 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 6 kg cat looks like

Six kilograms is about six 1-litre bottles of water. Some large-framed cats are healthy at this weight. For many others it is worth a vet's body condition check before choosing a calorie target, because feeding to a heavy weight keeps the weight on.

The engine's weight-loss figure uses the cat's current weight, so for a 6 kg cat it is 268 kcal a day, which is resting energy. It is not an ideal-weight calculation; ask your vet for a target weight and a safe pace. Starting point, not veterinary advice.

How much food is that? A worked example

As an example only, with a wet cat food with 90 kcal per 100 g, 322 kcal a day for a neutered or spayed adult is 358 g a day, or 179 g in each of 2 meals. Your food will have a different energy value, so read your own label. Starting point, not veterinary advice.

Every treat counts at this weight. The common guidance of about 10% of the day for treats (ask your vet) is about 32 kcal here, and ask your vet whether any treat allowance is right while a cat is losing weight. Starting point, not veterinary advice.

Puzzle feeders and slow feeders can stretch out mealtime and add a little activity for a larger cat. Whatever you use, weigh the food and keep track of the day's total, including any wet food.

Day-to-day feeding at 6 kg

If your vet does recommend a lower amount for a 6 kg cat, write the new daily total in calories, not scoops, and put it where everyone who feeds the cat can see it. Cats are quick to ask for more, so agree who feeds and when. A household that follows one number (here the neutered adult starting point is 322 kcal and the weight-loss figure 268 kcal) is far less likely to double feed than one that guesses. A written log or a shared app does the same job. Starting point, not veterinary advice.

6 kg in pounds

6 kg (13.23 lb). The calculator takes pounds as well and converts them exactly (1 lb is 0.45359237 kg) before it calculates. For example, 13 lb is 5.9 kg, which gives 318 kcal a day for a neutered or spayed adult cat at moderate activity. Starting point, not veterinary advice.

How 6 kg compares with nearby weights

  • Lighter: a 5 kg cat needs 41 kcal less a day than a 6 kg cat (281 versus 322 for a neutered or spayed adult at moderate activity), which is 13% less energy for 17% less body weight. Starting point, not veterinary advice. See the 5 kg cat page.

Not exactly 6 kg? The cat calorie calculator works out any weight from 0.2 to 120 kg.

Got questions?

6 kg cat calories: questions

How many calories should a 6 kg cat eat per day?

A 6 kg neutered or spayed adult cat at moderate activity needs about 322 kcal a day, and an intact adult about 376 kcal. At low activity the neutered figure is 268 kcal. A weight-loss goal for an adult uses the resting energy of the current weight, 268 kcal. Starting point, not veterinary advice.

How much food does a 6 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 90 kcal per 100 g would mean 358 g a day (179 g per meal over 2 meals) to supply the 322 kcal that a neutered or spayed adult cat of 6 kg needs at moderate activity. Measure by weight if you can. Starting point, not veterinary advice.

Should I feed a 6 kg cat the same as a 4 kg cat?

No. The engine estimates 322 kcal a day for a 6 kg neutered or spayed adult at moderate activity and 238 kcal for a 4 kg one. But if the 6 kg cat is above a healthy weight, feeding for its current weight keeps it there, so ask your vet what weight to aim for. Starting point, not veterinary advice.

How often should I weigh a 6 kg cat?

Every few weeks is a common routine, on the same scale at the same time of day, and a vet clinic scale is the most accurate. Write the number down. If weight changes when it should not, adjust portions by about 10% with your vet's guidance, and call the clinic about any sudden change.
