Quick answer: Kittens need a food labeled as complete and balanced for growth (or “all life stages”) under AAFCO standards in the US. Dry kitten food can be part of a healthy diet, and many vets recommend mixing in wet food for extra water and variety. Very young kittens do best with moistened kibble or wet food. Feed several small meals a day, and continue kitten food until about 12 months, or longer for large breeds like Maine Coons.
What kittens need
- More calories, protein, and fat per pound than adult cats
- Essential nutrients like taurine, which cats can’t make enough of
- DHA for brain and eye development
- Correct balance of calcium and phosphorus for bones
How to choose a food
- Look for an AAFCO statement that the food is complete and balanced for growth or all life stages.
- Prefer brands that meet WSAVA guidance: they employ qualified nutritionists, conduct research, and have strong quality control.
- Don’t rely on marketing terms like “grain-free,” “natural,” or “holistic,” which don’t guarantee better nutrition.
Dry, wet, or both?
- Dry food: convenient, affordable, and easy to use in puzzle feeders.
- Wet food: adds water, which supports urinary health, and helps kittens accept different textures.
- A mix of both is a common, practical choice.
Feeding by age
- 4–8 weeks (weaning): kitten food softened with warm water into a gruel, gradually thickening.
- 8 weeks to 6 months: about 3–4 small meals a day.
- 6–12 months: 2–3 meals a day.
- About 12 months: switch to adult food gradually over 7–10 days. Large breeds may stay on kitten food longer, as your vet advises.
How much to feed
Start with the label’s guide for your kitten’s age and weight, then adjust to keep a lean, healthy body. Weigh your kitten regularly and ask your vet to check body condition at vaccine visits. Treats should be no more than 10% of daily calories.
Common mistakes
- Feeding adult cat food or dog food: not balanced for growth, and dog food lacks enough taurine.
- Cow’s milk: most cats are lactose intolerant, and it can cause diarrhea.
- Raw diets: risk of Salmonella and other bacteria for kittens and people.
- Sudden food changes, which can upset the stomach.
- Homemade diets without a veterinary nutritionist.
When to call your vet
Call if your kitten stops eating, has diarrhea for more than a day, vomits repeatedly, or isn’t gaining weight. Young kittens can become ill quickly.
Frequently asked questions
Can kittens eat only dry food?
Yes, if it’s complete and balanced for growth, with fresh water always available. Adding wet food is often recommended.
Should I free-feed my kitten?
Young kittens often need frequent access to food. As they grow, scheduled meals help prevent overeating.
