How we picked the best kitten food

While shopping for kitten food, veterinarians recommend thinking about the following factors.

  • AAFCO nutrition standards: Ensure you buy kitten food that meets AAFCO nutrition standards. You can determine this by looking at the nutritional adequacy statement printed on the label. It should note that the food is either “complete and balanced for growth” or “complete and balanced for all life stages.” This ensures that the food you buy is formulated to address kittens’ nutritional needs and has been tested for efficacy and safety.
  • Ingredients: On a food label, ingredients are listed by weight from highest to lowest, which means the first three are the most important to consider, according to the AAFCO. Look for meat (including fish) as the first ingredient in your kitten’s food, and make sure it contains some source of DHA, an omega-3 fatty acid, like fish oil, says Dr. John Loftus, an assistant professor of small animal internal medicine and nutrition at Cornell University College of Veterinary Science. Kitten food should also have appropriate levels of nutrients like calcium, phosphorus, vitamin E, taurine (an amino acid) and fiber, says Dr. Hannah Hart, a veterinarian at Chewy.
  • Food type: You’ll see wet and dry food while shopping, and cats of all ages should eat both daily if possible, says Dr. Abel Gonzalez, a veterinarian and the clinical director at a Dutch pet telehealth company. Wet food is high in water content and helps with hydration, while dry food is crunchy and supports kittens’ dental health.
  • Availability: Kittens sometimes eat up to four times a day, so you’ll need a constant supply of food at home. Can you get it at a store in a pinch, or is it only available online? And if it’s only available online, how long does delivery from your preferred retailer typically take? Kittens can get an upset stomach if you suddenly change their food, so make sure you always have access to whatever you feed them. Some retailers offer cat food subscription services if you want to set up scheduled deliveries regularly.
  • Price: Experts told us that the price of kitten food does not always correlate with quality. Focus on finding one within your budget that your kitten enjoys eating, meets AAFCO nutrition standards and is made with healthy ingredients.

How to shop for the best kitten foodAAFCO nutrition standards

The Association of American Feed Control Officials (AAFCO) is a non-profit organization that establishes nutrition standards for pet food and labeling standards for different life stages. Pet food companies formulate and test their products against these standards to ensure they’re “complete and balanced” — this means the food contains necessary nutrients in the correct ratios, according to the AAFCO. The nutrient quantities and ratios necessary for each life stage vary, so the AAFCO’s nutrition standards differ accordingly. For example, growing pets, meaning puppies and kittens, need more calorie-rich food that may cause less active adult animals to become overweight.

That said, make sure the kitten food you buy meets AAFCO nutrition standards. You can determine this by looking at the nutritional adequacy statement on the label. It’s usually in small print on the back or sides of the package. The label should note that the food is “complete and balanced for growth,” meaning designed for kittens only, or “complete and balanced for all life stages,” meaning designed for cats of all ages.

Ingredients

Experts told us that as long as you buy kitten food that meets AAFCO standards, all the ingredients are safe and each serving offers a complete, balanced meal. But if you want to know more about exactly what the food is made from, read the nutrition label with the following in mind.

  • Protein (ideally 35% to 50%): On a food label, ingredients are listed by weight from highest to lowest. When it comes to kitten food, protein should always be the first ingredient, meaning it makes up the bulk of the recipe, says Hart. Protein is important for kittens to eat at high volumes because it helps ensure proper bone and lean muscle growth.
  • Fats (ideally 18% to 35%): The kitten food you buy should contain some fat, like DHA, an omega-3 fatty acid.
  • Calcium (ideally 0.8% to 1.6%) and phosphorus: Hart says kitten food with sufficient calcium and phosphorus ensures proper bone development. The calcium level is usually higher than the phosphorus level.
  • Other important nutrients: Other important nutrients are vitamin A, which helps with growth, muscle and neurological development, and vitamin E, which supports the immune system, says Hart. Kitten food also needs to have taurine, an amino acid that strengthens the heart and supports healthy blood flow, among other benefits. Fiber, which supports digestive health, is crucial too.

Hart says the protein and fat content in wet kitten food might be falsely low because moisture is accounted for. Your vet can help you determine if a kitten’s food meets the appropriate protein and fat percentages on a dry matter basis, meaning the percentage without accounting for moisture.

Food type

Should kittens eat dry food, wet food or both? This is a common question among cat parents. Ideally, cats, regardless of their age, should eat wet and dry food daily because each type offers different benefits. Loftus says that exposing kittens to wet and dry food early in life can also help reduce food aversions later on.

  • Wet food is high in water content and helps cats get extra moisture into their diet. This is important since cats don’t naturally drink a lot of water but need it to maintain proper kidney function, says Hart.
  • Dry food typically has more carbohydrates than wet food, and it’s beneficial for cats’ dental health. Its abrasive texture helps scrape plaque and tartar off cats’ teeth as they chew, says Hart. You can also use dry food as cat treats or put it inside puzzle toys, which keeps kittens mentally engaged as they work for food.
How to feed your kitten

Once you’ve picked out wet and dry food, you should determine how much and how often you should feed your kitten. Below, experts share their tips.

How much food do I feed my kitten?

How much food you need to feed your kitten changes as they grow and age, and factors like their breed, growth rate and overall health status contribute. That means there’s no hard-and-fast rule for how much food to feed your kitten, so talk to your vet about what they recommend. The nutrition label on cat food packaging offers serving size guidelines based on cats’ size and weight, a great reference point, says Gonzalez.

How often should I feed my kitten?

Regarding feeding frequency for kittens, you have three options: meal feeding, free feeding and combination feeding.

Meal feeding

Meal feeding involves feeding your kitten a few small meals daily, giving them wet and dry food at specific times to create a consistent schedule. You can experiment with the exact time of feedings to figure out when they tend to get hungry. Kittens ages zero to six months typically need to eat two to three meals a day, but some may require meals every six to eight hours, which could end up being three to four meals a day, says Hart. Starting at six months old, you can just feed your kitten twice a day, says Loftus.

Free feeding

Free feeding involves making food available to your kitten at all times. You can only free-feed dry food, however. You should not leave wet food out for more than four hours because it can grow bacteria and dry out, which may make it less appetizing to your kitten and can deter them from eating it again in the future, says Hart. If you’re free-feeding dry food, discard anything that hasn’t been eaten every 24 hours and replace it with fresh kibble.

The main downside to free-feeding kittens is that it can cause them to gain unhealthy weight early in life, potentially predisposing them to health conditions later on, says Hart. Kitten food is higher in fat and calorie count than adult cat food, so serving them limited portions prevents overeating. But as long as you monitor their body condition to ensure they’re gaining weight appropriately and have an ideal muscle-to-body fat ratio as they reach maturity, free feeding can be a great option for some kittens, experts told us.

Combination feeding

Some kittens are grazers, meaning they don’t like to eat all their food at once and prefer to nibble a little bit at a time, says Loftus. If that’s the case, combination feeding might be their best option. You can free-feed dry food, leaving a measured portion out all day so your kitten can eat whenever they want, and meal-feed wet food, giving your kitten a small portion twice a day at specific times. I’ve always fed my cats this way, and it’s worked very well for both of them. But every cat is different, so pay attention to their eating habits and feed them accordingly.

Frequently asked questions

The main difference between cat food and kitten food is the proportion of nutrients each is made with. Kitten food has higher levels of protein, fat, calcium, and phosphorus compared to adult cat food to support young cats’ growth and development, says Loftus. Adult cat food also lacks DHA and other fatty acids that are essential to kittens’ brain and eye development. Because of this, experts told us kittens should not routinely eat adult cat food.

Some cat food is formulated to meet the nutritional needs of kittens and adult cats — it’s labeled cat food for “all life stages.” However, one serving of cat food for all life stages tends to be less calorically dense than one serving of kitten food, which may mean you’ll need to feed your kitten more often.

You can usually transition your kitten to adult food when they’re about one year old or when they’ve reached maturity and stopped growing, says Loftus. Some cats reach maturity later than one year old, like Maine Coon cats, which is a large breed. Talk to your vet about what they recommend for your kitten before transitioning.

Loftus recommends changing your cat’s food over a five- to seven-day period or even slower if they have a particularly sensitive stomach. He recommends transitioning a cat’s diet from kitten to adult food in quarters. On day one, feed them 1/4 of the new food and 3/4 of their old food, gradually increasing to 100% of the new food over time.

Just like kids, kittens can be picky about their food. While this can certainly be due to general pickiness, it could also be an indicator of illness, says Loftus. So before you try anything else, be sure to have your kitten examined by their vet to rule out parasites or infections that could affect their appetite. If the vet gives your kitten a clean bill of health, you can try a few different strategies to make eating more pleasurable for them.

  1. Ask whoever was taking care of your kitten before you what type of food they were eating when they were weaned from their mother. If a kitten was exposed to a specific flavor, texture or shape of food early in life, they may have formed a preference for it, says Hart. If you can get this information, you can try to find that exact food or something close to it.
  2. Offer them different options until you find something they like, and then stick to it, says Gonzalez. Wet and dry kitten food comes in various flavors and textures, so consider experimenting with a few. He says you can also try warming up wet food, which some cats find more appealing.
  3. Hart suggests mixing kittens’ food with toppers to entice them, such as low-sodium unseasoned chicken broth, plain scrambled eggs or egg whites.
  4. Adjust your kitten’s feeding schedule. Some kittens may prefer to eat multiple small meals throughout the day instead of larger meals in the morning and evening. As long as they eat an appropriate amount of food daily, you can break up servings however they prefer.
  5. Change where you’re feeding your kitten in your home. When one of my kittens would not eat, I realized it might be because of a noisy air conditioner near her food bowl. I moved her bowl further away and she ate her food immediately.

Yes, grain-free diets can be safe for kittens or cats of any age, so long as they’re still eating sufficient levels of carbohydrates, vitamins and minerals, experts told us. “Grain-free” is a claim some brands add to their foods’ labels when made without wheat, barley, rye, corn, millet, rice or oats. Some people think a grain-free diet is healthier for cats because wild cats don’t eat these types of grains, so they believe domestic cats don’t need them either, says Hart. However, grains are an important source of carbohydrates for energy, as well as vitamins and minerals like iron, calcium and vitamin B, which are essential for proper organ function.

Experts told us that if you work with your vet to find a complete and balanced grain-free food, it’s safe for your kitten to eat. “The FDA is still investigating the link between feeding grain-free diets and heart disease in dogs, but no such link appears to exist in cats,” says Hart. “Thus, there does not appear to be a risk in feeding grain-free foods to kittens at this time.”

No, raw food diets are not safe for kittens or cats of any age. All the experts we spoke to recommend against feeding your cat a raw food diet, as does the American Veterinary Medical Association . A raw food diet is centered around ingredients that are not cooked or otherwise heat treated, which some people believe is healthier to feed cats because ingredients are closer to their natural forms, closely mimicking the diet of wild cats, says Hart. But because raw food diets contain uncooked eggs and meat, there’s a high risk of foodborne illness for the cat eating it and the person serving it, says Loftus.
