Feeding & Nutrition

A kitten triples its birth weight in the first few weeks and reaches most of its adult size by nine months. Compressing that much construction work into a short period takes a serious amount of fuel, and it is why kitten food exists as a separate category rather than as a marketing exercise.

Get the first year right and you set up a cat that is well muscled, correctly sized and free of the habits that create fussy or overweight adults later.

Before eight weeks

Kittens should stay with the mother until at least eight weeks, ideally twelve. Queen's milk provides antibodies in the first days that nothing else replicates.

If you have orphaned kittens, cow's milk is not an option. It causes diarrhoea and lacks the nutrients they need. Kitten milk replacer, fed at body temperature with a proper kitten bottle, is the only appropriate choice. Very young kittens feed every two to three hours around the clock, dropping to every four to five hours by three weeks. They also need stimulating to toilet after each feed with a warm damp cloth until about three weeks old, which the mother would normally do.

Weaning starts around three to four weeks. Offer a gruel of wet kitten food mixed with warm milk replacer in a shallow dish. Expect it to be worn rather than eaten for the first few days. Gradually thicken the mixture, and most kittens are eating solid food properly by six to eight weeks.

How much, how often

Kittens have small stomachs and enormous energy requirements, so frequency matters as much as quantity.

From weaning to about four months, feed four meals a day. From four to six months, three meals a day works well. From six months to a year, two or three meals a day is appropriate, and most cats settle into twice daily as adults.

Quantity depends on the food, so start with the manufacturer's guideline for the kitten's current weight and expected adult weight, then adjust based on body condition. A growing kitten should feel well covered but you should still be able to feel the ribs without pressing. Weigh weekly if you can; steady gain is the goal, not the fastest gain possible.

As a rough sense of scale, kittens need roughly two to three times the calories per kilogram of body weight that an adult cat needs. That falls away as growth slows.

Free feeding dry food is a common approach and it works for some kittens, particularly very young ones who need frequent small meals. The trouble is that it makes portion control invisible and often carries straight into adulthood, where it is a leading contributor to feline obesity. Scheduled meals give you information and control, and they make it far easier to notice the day your cat goes off its food.

Wet, dry, or both

Both formats can be complete and balanced if the label says so. The practical case for including wet food is water. Cats evolved from desert animals with a weak thirst drive, taking most of their moisture from prey. Wet food is around 75 to 80 percent water; dry food is around ten. Kittens raised on some wet food develop the habit of eating it, which becomes valuable if they ever need a therapeutic wet diet for kidney or urinary problems as adults.

Dry food is convenient, keeps well and can be used in puzzle feeders. Many owners do a mix: measured wet meals plus a portion of dry.

Whatever you choose, look for a statement on the packaging confirming the food is complete and balanced for growth or for all life stages, meeting an established nutritional standard. That single line matters more than any of the marketing on the front.

What kittens genuinely need

Protein levels for growth are high, and cats are obligate carnivores, meaning they cannot thrive on plant protein alone. Taurine, an amino acid found in animal tissue, is essential; deficiency causes heart disease and blindness, and this is a large part of why vegetarian diets are inappropriate for cats.

Arachidonic acid and preformed vitamin A must come from animal sources, since cats cannot manufacture them the way dogs and humans can. DHA supports brain and retinal development in kittens and is included in good kitten formulas.

The calcium to phosphorus ratio matters for skeletal development, which is another reason not to improvise a homemade diet for a growing animal without professional formulation.

Things to keep out of the bowl

Cow's milk causes diarrhoea in most cats beyond weaning, since they lose the ability to digest lactose. The saucer of milk is a picture-book image, not good practice.

Dog food is not a substitute even briefly. It lacks the taurine and vitamin A levels cats require.

Raw diets for kittens carry more risk than for adults, because immature immune systems handle salmonella and campylobacter poorly, and homemade raw recipes are frequently unbalanced during a period when balance matters most.

Onion, garlic, chocolate, grapes, raisins, alcohol and xylitol are toxic. Cooked bones splinter. Tuna intended for humans is fine as an occasional treat but is not balanced and can encourage extremely fussy eating.

Building good habits early

Introduce variety in the first six months. Cats form flavour and texture preferences young, and a kitten exposed only to one flavour of one brand of dry food often becomes an adult that refuses everything else. Rotating between two or three flavours and both formats builds flexibility that pays off later.

Feed in a quiet spot away from the litter tray, and use a shallow wide dish, since many cats dislike their whiskers touching the sides of a deep bowl. In multi-cat homes, separate feeding stations prevent competition and let you monitor individual intake.

Treats should stay under ten percent of daily calories, and they count toward the total. It is easy to overfeed a two-kilogram animal with what looks like a tiny snack.

Fresh water should be available at all times, in a bowl away from the food, and many cats drink more from a fountain.

Making the switch to adult food

Most cats move to adult food at around twelve months. Large slow-maturing breeds such as Maine Coons and Ragdolls benefit from kitten food until eighteen months to two years, since they are still growing.

Transition over a week to ten days by mixing increasing amounts of the new food. And adjust portions downward, because a neutered adult cat needs considerably fewer calories than a growing kitten and the weight creeps on quietly if you keep feeding at kitten volumes.

Then keep checking body condition every month. The single most common nutritional problem in adult cats is obesity, and it almost always begins with a well-intentioned owner still feeding a kitten that grew up.
