How Much Wet Food to Feed a Cat Per Day? A Guide by Weight

By Haven Bowl

Short answer: Most healthy adult cats eat about 200 to 300 calories a day, according to the World Small Animal Veterinary Association (WSAVA). For a wet food near 33 calories an ounce, that is roughly 6 to 10 ounces, split into two meals. A 10-pound cat needs about 240 to 270 calories. Check your food's label, since recipes differ.

Rules of thumb like "one can per three pounds" sound simple, but cans come in different sizes and recipes carry different calories. Counting calories is the steadier way to answer "how much wet food does my cat need?" Here is how to do it in five minutes.

How much wet food to feed a cat per day by weight?

The WSAVA Global Nutrition Committee publishes calorie ranges for an average healthy adult cat in ideal body condition. The table below uses those ranges. The ounces column uses one example food: PetMD, in an article by Barri J. Morrison, DVM, lists a canned chicken food at around 181 calories per 5.5-ounce can, which is about 33 calories per ounce.

Cat's ideal weight Calories per day (WSAVA) Ounces per day of a food at ~33 calories per ounce
6.6 lb (3 kg) 200 to 210 about 6 to 6.5 oz
8.8 lb (4 kg) 225 to 250 about 7 to 7.5 oz
9.9 lb (4.5 kg) 240 to 270 about 7 to 8 oz
11 lb (5 kg) 250 to 290 about 7.5 to 9 oz
13.2 lb (6 kg) 265 to 330 about 8 to 10 oz

WSAVA is clear that these are for guidance only. Some cats need more or less to stay trim. Use the row for your cat's ideal weight, not the number on the scale, if your cat is carrying extra.

How many cans or pouches of wet food is that?

Ounces only help if you know your food's calories. Look for the calorie statement on the label, usually kcal per can, pouch or kilogram. Then it is one division:

  1. Find your cat's daily calories in the table above, or ask your vet for a number.
  2. Find the calories in one can or pouch on the label.
  3. Divide. Daily calories divided by calories per can or pouch gives cans or pouches a day.
  4. Split it into meals. PetMD's example splits a 10-pound cat's day into two meals.

Take the 181-calorie can from the PetMD example. A 10-pound cat at 250 calories a day needs about 1.4 cans, or roughly 7.6 ounces. A small pouch with fewer calories will take more servings. The label on your own food is the number that counts.

Is one can of wet food a day enough for a cat?

Often, no, if wet food is the whole diet. One 181-calorie can covers roughly two-thirds to three-quarters of the 240 to 270 calories a 9.9-pound cat needs. If wet food is a topper over dry food, one can may be plenty. Everything the cat eats counts toward the same daily total.

How much wet food if my cat also eats dry food?

Count both. Say your cat needs about 250 calories a day and you want dry food to supply a fifth. That is about 50 calories of kibble, and the wet food covers the other 200. Tufts veterinary nutritionist Deborah Linder, DVM, recommends weighing pet food rather than using cups, because measuring by volume often leads to under- or overfeeding. AAHA also warns that free-choice feeding can predispose to overconsumption.

Treats count too. Cornell's rule of thumb is that treats should not exceed 10 to 15 percent of daily calories.

How many times a day should I feed my cat wet food?

Cornell says that once a cat reaches adulthood, at about one year, feeding once or twice a day is appropriate in most cases. Many households pick two meals, morning and evening, because it is easy to remember and keeps portions simple. Cornell also says the amounts on pet food labels are based on the average cat, so adjust for your cat's size and activity.

Wet food is typically 70 to 80 percent water, per Cornell, so it also adds to your cat's water intake. Our guide on whether cats need wet food covers that.

How do I know I'm feeding the right amount?

Your cat's body tells you more than the label does.

  • Weigh your cat every few weeks, at home or at the vet.
  • Check body condition. Vets use a 9-point score, where 5 is ideal. AAHA's guidelines call 6 or 7 out of 9 overweight and 8 or higher obese.
  • Adjust slowly. Change the daily amount by small steps and recheck in a few weeks.
  • Skip crash diets. If your cat needs to lose weight, ask your vet for a plan.

A yearly exam is a good time to check all this. See how often a cat should go to the vet for the schedule by life stage.

Do kittens need more wet food than adult cats?

Kittens eat more often. Cornell says kittens usually do best with three meals a day until they are six months old, then two a day until about one year. Their calorie needs also change quickly as they grow, so use a food made for kittens and follow your vet's advice. Our kitten feeding schedule by age has the details.

The bottom line

Skip the can-per-pound rules. Find your cat's calorie range, read the calories on the label, divide, and split the result into one or two meals. Measure for a few weeks, watch your cat's weight, and let your vet fine-tune it.

Frequently asked questions

How much wet food should I feed my cat per day?

Most healthy adult cats need about 200 to 300 calories a day, per the WSAVA. For a food near 33 calories an ounce, that is roughly 6 to 10 ounces. Your cat's weight, activity and the food's calories change the answer, so read the label and ask your vet.

How many cans of wet food should a cat eat a day?

It depends on the can size and calories. One 5.5-ounce can with about 181 calories, PetMD's example, covers roughly two-thirds to three-quarters of a 10-pound cat's day, so most cats need more than one. Divide your cat's daily calories by the calories on the can.

How many times a day should I feed my cat wet food?

Cornell says feeding adult cats once or twice a day is appropriate in most cases. Many cat parents split the daily amount into two meals. Pick a schedule you can keep and ask your vet if your cat has special needs.

Can a cat eat only wet food?

Many cats do. Pick a wet food labeled for your cat's life stage, measure the calories, and keep fresh water out. Cornell notes wet cat food is typically 70 to 80 percent water. Ask your vet before changing your cat's diet.

How much wet food if my cat also eats dry food?

Count both toward one daily calorie total. If dry food supplies a share of the calories, the wet portion shrinks by the same share. A Tufts veterinary nutritionist recommends weighing food rather than using cups. Your vet can help you set the split.

How do I know if I am feeding my cat too much?

Ask your vet for your cat's body condition score. AAHA's guidelines call 6 out of 9 or 7 out of 9 overweight. Weigh your cat every few weeks, count treats, and do not start a diet without your vet.

Do kittens need more wet food than adult cats?

Kittens eat more often, and Cornell suggests three meals a day until six months. Their needs change quickly with growth, so use a kitten-specific food and follow your vet's advice. Our kitten feeding guide covers the schedule by age.
