Finding the best kitten food is going to be one of the first things you need to do when you plan to add a new fur baby into your home. As well as providing them with stimulating toys, fresh water, cat beds and cat litter, finding them the right nutrition to give them the best start in life will help your kitty grow up healthy, strong, and full of that rambunctious energy they are so well known for.

You'll already be aware if you've researched the best cat food for the other felines in your life that pet food comes in a variety of ingredients and prices. Your choice of kitten nutrition needs to provide them with all the protein, vitamins, minerals and antioxidants they need to help with their development – and their irrepressible energy to play and explore.

Once your kitty has weaned from their mother – typically at 6 to 8 weeks – they will be ready to eat on their own. And they will eat a surprising amount – you may find your cute furry friend will head for the cat bowl 3 to 4 times a day to eat a small portion. For this you can try 'free eating' where food is always available for them to snack on, but do monitor how much they are eating. Try not to limit it too much though: Kittens grow fast and increase their weight three-fold within the first month, so they need the right amount of calories to fuel this growth spurt.

The first thing you need to consider is the choice between dry or wet cat food – or, to get the benefits both provide, a combination of dry and wet. The best dry cat food, or kibble, has a crunch and a taste kittens go crazy for. The right dry food formulas will contain everything your kitty needs in their diet, so it can be used on its own. It's great for their teeth as its rough texture acts as a toothbrush and removes plaque, tartar and other tooth debris. Kibble also lasts longer, and so is safer to leave out for long periods. The downside is it contains little moisture, so you need to ensure your fur baby is getting enough hydration if this is their only source of food.

The best wet cat food on the other hand contains real meat and has a soft texture which is great for tiny teeth. As it's the kind of food your kitty would have eaten in the wild, they find it easy to digest. It is also filled with moisture, perfect to keep their urinary tract and kidneys in perfect working order. The downside is it is messy, more expensive, and will go off and start to smell bad if it is left sitting out for too long.

Whichever you choose, there are a few ingredients you need to ensure you are providing your little bundle of fun in their diet. Cats of any age are unable to produce the amino acid Taurine, and only produce limited amounts of Arginine, both of which are essential for their healthy growth. You will also need to provide them with a lot of Omega-3 DHA as this helps with their brain development. Calcium, too, is necessary to help them build strong bones and joints. 

To help you source what you need we've searched through all the different best kitten foods we could find so you can easily match your fur baby's needs and your budget. Let's go shopping!

Royal Canin Kitten

Best overall kitten food

Item Form: Wet (Gravy) | Protein: 11% min | Fat: 3% min | Moisture: 80% max

Thin slices make it easy for young kittens to eat
Excellent protein, fat, and carbohydrate ratio
Antioxidants boost immune system
High price point for a staple diet

If you’re keen to ensure that your new four-legged friend has a balanced and nutritious diet, it’s hard to look past Royal Canin’s Kitten food. 

Royal Canin is a hugely respected cat food brand, earning praise from owners and veterinarians alike for its specialist formulas. It may be a little pricier per can than others on this list, but there’s little substitute for knowing that you’ve got your kitty some quality dinner from a trusted brand. 

The ratio of proteins to fat and carbohydrates, and other essential nutrients, in Royal Canin’s Kitten food is perfectly set up to deliver everything a growing kitten needs. This means that unless you’ve found yourself a fussy little fluff ball who craves a bit more variety, Royal Canin can easily be your kittens-only food. Though it’s useful to note that Royal Canin’s dry kitten food is formulated to complement the wet stuff so you can add a bit of crunch to your little one’s diet.

The meat comes in gravy (which can be a bit messy), and is deliberately sliced small and thin to make it easier on tiny mouths transitioning to solid food.

Of course, we do have to return to that price point, a kitten will need to be going through three or four of these cans a day to get everything they need. That might mean it’s a little much for some people to keep as a staple diet – it is worth noting that Royal Canin is often prescribed for kittens with digestive issues though. So, as long as you manage it properly, Royal Canin Kitten food could work well as part of a regular rotation.

IAMS Proactive Health

Best budget kitten food

Item Form: Dry | Protein: 31% min | Fat: 21% min | Moisture: 10% max

Omega-3 DHA promotes brain development
Natural fiber and prebiotics
Taurine promotes strong vision
Contains animal by-products

Dry foods often work out on the cheaper side when it comes to cat and kitten foods, because you get so much of it in a pack. IAMS Proactive Health dry kitten food is well priced even among its direct competitors.

Affordability is IAMS whole thing. They’ve got a reputation for putting together solid, nutritionally strong pet food at a price that won’t put a strain on your wallet. This is not different.

The nutrition profile here is strong, with taurine to help develop your kitten’s vision, natural fibers and prebiotics for digestion, omega-3 DHA for promoting brain development and Vitamin E for boosting immune systems. 

Kittens seem to be big fans of IAMS Proactive Health’s taste but some pet owners might take issue with how the product is made. With the inclusion of animal by-products some people may have ethical concerns. 

This food isn’t grain-free, and while a small amount grain as part of a well-rounded diet shouldn’t be problem, it’s worth baring in mind for cat parents. It’s also worth noting that while this product does claim to be free of fillers (foods that bulk up a product while adding little nutritional value), corn grain and whole grain sorghum are ingredients that many consider to be fillers. 

Of course, that doesn’t take away from the fact that IAMS is a very popular and well-trusted brand. If those issues don’t affect you, then in IAMS Proactive Health you have a well-rounded, nutritious dry kitten food at a very reasonable price.

Royal Canin Feline Gastrointestinal Kitten Dry Cat Food

Royal Canin Feline Gastrointestinal Kitten Dry Cat Food

Best kitten food for sensitive stomachs

Item Form: Dry | Protein: 33% min | Fat: 22% min | Moisture: 8% max

Designed for cats with very sensitive stomachs
Smaller portions provide high nutrition
Contains fatty acids to soothe digestion
Vet recommended
Need vet consultation to buy
Expensive

If your kitty is recovering from surgery, or suffers regular stomach upsets and chronic diarrhea, you need to find a cat food that their sensitive stomachs can cope with. The same is true if they are finding the transition from their mother's milk to solid food an uphill struggle and are losing weight because of it. 

Royal Canin Feline Gastrointestinal Kitten Dry Cat Food is specifically designed to ensure your furball gets all the nutrition it needs, even if it is only able to eat smaller portions. It is also available as a soft mousse product – although the dry formula is designed for you to be able to add water to it for extra kitty hydration.

Note that because it is very high in fat and protein you need to get veterinary advice before you can buy this product. When Royal Canin says vet recommended, they mean it! It is specifically designed for kitties that can't eat much, and contains adapted levels of nutrients, including protein and calcium to help support healthy digestion – which means a healthy cat would find it too much.

If your vet agrees though, users have called it a godsend. The formula includes fish oil to provide Omega-3 fatty acids, EPA and DHA, to help soothe the gastrointestinal tract, while it's formula of digestible proteins and prebiotics support digestion and optimal stool quality. This combination allows it to act quickly, relieving your kitty's digestion issues in a matter of days. 

The downside is that it is very expensive, but if your kitty is finding normal foods difficult to eat and process, this is a very sensible investment to stop their suffering fast.

Nature’s Variety Instinct Original Kitten is the best raw kitten food for raw diets

Nature’s Variety Instinct Original Kitten

Best raw kitten food

Item Form: Dry | Protein: 42.5% min | Fat: 22.5% min | Moisture: 9% max

100% natural ingredients
Made without grain, potato, corn, wheat, soy, by-product meats, artificial colors, or preservatives
Made with cage-free chickens
Not enough moisture for kittens

It’s sometimes difficult to know what’s actually in the foods we feed our four-legged friends. Foods that make it easy for us are always welcome; Nature’s Variety’s commitment to raw ingredients make their Instinct Original Kitten dry kibble super easy to understand.

The Instinct range from Nature’s Variety is committed to 100% natural ingredients, although it might be easier to demonstrate the Original Kitten lines commitment to nutrition by first telling you what’s not in it. This dry kibble is grain free and contains no soy, wheat, corn, potato, by-product meals, artificial preservatives, or colors. 

81% of this kibble comes from real animal ingredients and oils, which puts its protein content at a whopping 42.5% and fat at 22%. That’s exactly what a calorie-hungry kitten needs. The food includes taurine, DHA, and probiotics for promoting everything from healthy brain and vision development to nice soft fur.

The remaining 19% of the product is made up from vegetables, fruits, and what Instinct calls ‘other wholesome ingredients, and while some have criticized the product for including ingredients like carrots, deeming them unnecessary, the kibbles nutritional profile is very strong.

Given this food’s raw and natural ideology, we think we’d be remiss in not mentioning that Instinct have had to issue recalls on their food twice for potential salmonella. The last of these coming in 2015 after a confirmed FDA test, though we have no reason to believe this is likely to happen again.

As with most dry cat foods, Instinct Original Kitten isn’t going to give your kitten all the water it needs so you may want to think about pairing this with a wet food rather than as your kitten’s sole diet.

Applaws Kitten Tuna Fillet in Broth is the best top quality kitten food

Applaws Tuna Wet Kitten Food

Best gourmet kitten food

Item Form: Wet (broth) | Protein: 13.5% min | Fat: 2% min | Moisture: 82.4% max

Dolphin-friendly tuna
High in protein
No artificial additives
Not nutritionally complete

You could be forgiven for being skeptical when a brand claims to supply everything your kitten needs – most of them are doing that, after all. Refreshingly, Applaws isn’t one of them. Instead, it has built its reputation on creating fresh tasty meals that are designed be part of a well-rounded diet, rather than a staple of it.

Applaws’ whole brand is centered around using simple ingredients that haven't been tampered with, using human-grade meat with no artificial flavors, colors, or preservatives. Indeed, very little of anything is added. For example, the Applaws Kitten Tuna Fillet in Broth had just three ingredients; tuna fillet, fish broth, and rice. This way, you're left in no doubt as to exactly what you're getting.

While this is all great, like we said previously, this isn't a staple, so you shouldn't be providing it in every meal. It simply doesn't provide everything your kitten should be consuming as part of a balanced diet, so this high-protein tin should be treated as a gourmet treat rather than something to be included with absolutely every meal.

Moreover, this additional treat doesn't come cheap, and you'll find that the cost mounts up with every 24 cans you buy – quite a lot more than is normally the case with many other brands, in fact. Regardless, what you're getting for this is a protein-rich gourmet experience for your kitten, and there's nothing wrong with treating them once in a while. As long as you only dish these out once a day at most, you'll get plenty of longevity out of it, and your mini cats will definitely thank you for it.

Best kitten food: Nutro Wholesome Essentials Kitten Dry Cat Food

Nutro Wholesome Essentials Kitten Dry Cat Food

Best natural kitten food

Item form: Dry | Protein: 36% | Fat: 19% | Moisture: 10%

Quality ingredients
Extensive range of vitamins, minerals, and antioxidants
Free from common allergens 
Pricier than many other brands

If you're looking for a clean and natural formula that uses high quality ingredients, then this real food kibble from Nutro is well worth parting with your pennies for.

While the 5lb bag is more expensive than many other brands, this is definitely a case of getting what you pay for. With real chicken as the number one ingredient and source of protein and nourishing brown rice as a filling carbohydrate, this kibble has everything your new kitten needs to thrive.

You'll find an extensive list of included vitamins, minerals, and antioxidants, including plenty of omega-3 fatty acids for growth and development and calcium for strong bones and joints. We love the addition of beet pulp too, which provides a good hit of fiber and will help keep your kitten's digestive system running smoothly.

The limited ingredient list means there's little chance of this kibble causing any kind of allergic reaction in your kitten. It's free from corn, wheat, and soy, as well as all artificial colors, flavors, and preservatives. There's no chicken by-products here either, which is really great to see.

Overall, this is a complete, nutritious, and balanced formula that's getting rave reviews from both pet parents and their young feline furkids. If your budget can stretch to the extra cost, we think this one is definitely a worthy contender of a place in your shopping cart. 

Purina Pro Plan Kitten comes in many varieties

Purina Pro Plan Kitten Favorites

Best variety kitten food

Item Form: Wet (Pate) | Protein: 12-13% min | Fat: 5-6% min | Moisture: 76.5% max

Made with real poultry and fish
3 meaty flavors
DHA for brain and vision development
Larger meat chunks

Many kitten food brands these days tend to stick to one or two products that they identify as the best things you should be feeding your little meow machine. This is a great approach that allows a consumer to know, pretty much, exactly what they’re getting – but for the little ones, it can get a bit samey. Purina’s Prop Plan Kitten Favorites variety pack has 3 flavors to choose from. Variety is the spice of life after all.

The three flavors, Chicken & Liver, Ocean Whitefish & Tuna, and Salmon & Oceanfish are made with real poultry and fish as the number one ingredient. They add taurine for eyesight and DHA for brain development, as well as a blend of vitamins and nutrients to develop a healthy immune system. 

There is a slight difference in protein and fat between the chicken and fish flavors – with the Chicken & Liver having slightly less protein and slightly more fat – but all within what works for healthy kitten growth. 

However, some people have had trouble with larger meat chunks in the pate, meaning their kittens struggle or give up. Not all kittens have a problem with larger chunks, but if yours do, this might be one to wait until they’re a little bigger. 

Lastly we’ll point out the perennial problem with variety packs: you may end up with a flavor your kitten doesn’t like. This will happen to us all at some point but sometimes kittens don’t react well to the unfamiliar, so either try introducing the flavor again slowly with another or find yourself a fellow cat parent to swap foods with. Either way, the benefit of a variety pack is that you wont be wasting the whole case.

Royal Canin Mother & Babycat Ultra-Soft Mousse

Best kitten food for weaning

Item Form: Wet | Protein: 9% min | Fat: 4% min | Moisture: 81% max

Soft mousse texture
Contains DHA for brain development
Ideal for pregnant or nursing mother cats too
High price point for a staple diet

If you're looking to gradually introduce your young kitten to kitten food, then Royal Canin Mother & Babycat Ultra-Soft Mousse is a great choice. It features a soft mousse-like texture which makes it easy for both kittens and nursing mothers to consume. It's a bit like pâté in consistency; this wet kitten food is ideal for supporting healthy hydration.

As a specialist product for mother and kitten, Royal Canin look to pack a few extras in the can. There's the inclusion of nutrient DHA, which studies have shown helps brain and vision development in kittens, as well as additional vitamins including Vitamin E, B1 and B6.

Essentially, there's everything here your kitten needs to get the best nutritional start in life - providing you're willing to fork out a little extra.

Royal Canin can be a little pricier than some other leading brands and once your kitten has had their daily fill, that could really start to add up. 

Fortunately, however, there are few a options. The brand does offer the cans in multipacks of 6-24, making it a great way to stock up in advance to feed hungry mouths. 

How to choose the best kitten food

When choosing the best kitten food, there are several things you need to think about. 

Firstly, nutrition. You want to make sure you’re hitting the right protein to fat ratio, and getting enough of both. For dry food you want to be hitting more than 30% in protein content and 15-20% in fat. For wet foods you ideally want between 10-15% for protein and around 3-6% for fat. 

You may want to be more aware of foods with high grain content, while the debate rages about exactly how bad grain are for cats, they can be an indicator that a food is full of filler or high in difficult to digest carbohydrates, rather than all the more preferable ingredients for a kittens development. 

When it comes to intolerances and allergies, it’s actually fish, chicken beef and dairy products that are the most common in felines. So while you should expect to see a little bit of a digestive reaction to any new food, if it goes on too long you may want to investigate further.

Ideally, you’ll pick out a mix of dry and wet woods. While dry food can be more cost effective and easier to manage, it won’t provide the moisture your cat needs to stay hydrated. If you’re going dry only, make sure your house is full of water sources for your cat to find, though they’ll need to be refreshed daily.

Lastly, the best kitten foods will recommend a transition period when switching. This will avoid most cases of digestive distress which, if prolonged, can be dangerous to kittens. Take a week, and slowly introduce the new food alongside the old to allow their systems to get used to it. Of course, if your kitten seems to be experiencing problems, or you’re worried that they may have a food sensitivity or other health problem, consult your vet.
