Feeding a kitten: food, amounts and timing

How to choose kitten food, how often to feed through the first year, wet versus dry, water and weight checks, and the signs that call for a vet.

Feed a growing kitten a food labelled as complete and balanced for growth, in several small meals a day, with fresh water always available. Follow the amounts on the label as a starting point and adjust with your vet by watching the kitten's weight and body shape. Switch to an adult diet only when your vet says the kitten is ready.

Kittens grow fast. They need more energy and protein for their size than adult cats, and they need the right balance of calcium, phosphorus and other nutrients to build bone and muscle. A food that suits an adult cat may not supply enough.

Choose the food

Look for the statement on the label. A kitten food, or a food labelled for all life stages, states that it is complete and balanced for growth. The wording and standards differ from country to country, so read the label closely. A food that does not give this statement is not suitable as a main diet.

You can feed wet food, dry food or a mixture. Each has advantages.

  • Wet food contains a lot of water, which helps with hydration, and many kittens like it. It is more expensive per meal and spoils if it sits out.
  • Dry food is convenient and keeps well. Cats on dry food only should drink plenty of water, and it is easy to overfeed.
  • A mix combines both. Many owners find this practical.

Ask your vet before choosing a raw, homemade or vegetarian diet. Cats are obligate carnivores, and an unbalanced homemade diet can damage a growing kitten's bones and organs. Raw food can also carry germs that make cats and people ill.

Do not choose by brand loyalty or marketing words alone. Compare labels, ask your vet and watch how the kitten does.

What the kitten was eating

Find out what the kitten ate before it came to you, and feed the same food for the first days. If you want to change, mix the new food into the old over seven to ten days, a little more each day. A sudden change can upset the stomach and make a kitten refuse food.

How often to feed

Younger kittens have small stomachs and need frequent meals. As a rough guide:

  • Around weaning, up to about 8 weeks: several small meals, often four or more a day. weaning is the move from milk to solid food, and most kittens finish by about eight weeks.
  • About 8 to 12 weeks: three or four meals a day.
  • About 3 to 6 months: three meals a day, then moving toward two.
  • About 6 months and over: two meals a day. Many cats keep this pattern for life.

These are common patterns and not rules. Ask your vet what suits your kitten, especially if it is small, ill or a breed that grows slowly.

Meal times help you notice a kitten that is off its food. Free feeding, where food is always out, hides changes in appetite and makes it harder to prevent overweight. If you leave dry food out, measure the day's portion.

How much to feed

The label gives a range by weight or age. Use it as a starting point, then adjust. The cat feeding calculator tool gives an estimate of daily energy needs and a way to split the portions. Remember that:

  • Treats count toward the total. Keep them to a small part of the day's food.
  • Wet and dry food have different amounts of energy, so weigh or measure each.
  • Kittens are individuals. Two kittens of the same age can need different amounts.

Weigh the kitten every week or two on a kitchen scale, and write the weight down. The kitten schedule tool helps you track age-based milestones. A healthy kitten gains weight steadily. Look at the shape as well. From above you should see a gentle waist. You should be able to feel the ribs under a thin layer of padding. The body condition score glossary entry describes the scale vets use. If the kitten looks round or bony, or the weight stalls or jumps, talk to your vet before changing the amount.

Do not put a kitten on a diet. Growth is the priority. Overfeeding young cats can lead to obesity later. Your vet will guide the balance.

Water

Provide fresh water at all times in a clean bowl. Some cats prefer a wide, shallow dish, a fountain or several bowls. Keep water away from the litter box and the food. Do not give cow's milk. Many cats cannot digest it and it can cause diarrhoea.

When to move to adult food

Most kittens move to an adult diet at about one year, though some large breeds grow for longer. Do not change on a fixed date. Ask your vet at a check-up. Switching too early can leave a growing cat short of nutrients. Switching too late can add unnecessary calories. When you do change, use the gradual mix described above.

Neutered kittens

Spaying or neutering changes energy needs, and many neutered cats gain weight more easily. Ask your vet when to adjust portions and whether to change to a diet for neutered cats. Do this on the vet's advice and not by guesswork.

Common mistakes

  • Feeding adult food too soon.
  • Leaving food out all day without measuring.
  • Giving too many treats or table scraps. Some human foods are toxic to cats, such as onions, garlic, chocolate, grapes and raisins.
  • Giving milk.
  • Changing food suddenly.
  • Adding supplements on your own. Extra calcium or vitamins can harm a growing kitten. Ask your vet.
  • Ignoring weight. Weigh at set times.
  • Feeding from a dirty bowl. Wash bowls daily.
  • Leaving wet food out for hours. Throw away what is not eaten within the time on the label.

When to call a vet

Call your vet the same day if the kitten:

  • Refuses food for a meal or two, or for any part of a day. Kittens have little reserve.
  • Vomits more than once, or has diarrhoea that lasts more than a day or contains blood.
  • Seems weak, cold or limp.
  • Drinks far more than usual, or hardly at all.
  • Loses weight, or fails to gain it for a couple of weeks.
  • Chokes, gags or drools when eating.
  • Has a swollen belly.
  • Strains in the litter box.

For a male kitten that strains to pass urine or passes none, go to an emergency clinic at once.

Summary

  • Use a complete and balanced kitten food from a label you have read.
  • Feed several small meals and reduce them as the kitten grows.
  • Start with the label amounts, then adjust by weight and body shape.
  • Change foods slowly.
  • Keep water fresh and avoid milk.
  • Ask your vet before supplements, raw diets or the switch to adult food.

Terms used in this guide

Kitten food A food with more energy, protein, fat and minerals than adult food, made to support a kitten's fast growth. Complete and balanced A pet-food label claim that a food supplies all the nutrients a cat needs at a stated life stage, when used as the only diet. Wet food Cat food sold in cans, pouches or trays, containing roughly 70 to 80 percent water, which helps a cat get more fluid. Dry food Cat food baked or extruded into small pieces with about 10 percent water, convenient and shelf-stable but low in moisture. Weaning The gradual switch from mother's milk to solid food, which usually starts at about four weeks and is mostly complete by eight to ten weeks. Body condition score A hands-on rating of how lean or fat a cat is, on a scale such as 1 to 9, used by vets because weight alone can mislead.
