How Long Should Kittens Eat Kitten Food?

So, you finally brought home a kitten. Congratulations on adopting a little ball of endless energy, curiosity, and a whole lot of adorable mischief! Be prepared for endless days of fun and questions, especially if you’re a new fur parent. Among the many joys and responsibilities of kitten parenting is feeding. It’s satisfying to see your pet enjoy their food, but it’s also worrisome for new pet parents. One of the usual questions you may ask is: When should I switch from kitten food to adult cat food? Let’s answer this here!

When Should Cats Stop Eating Kitten Food?

Kittens should stop eating kitten food around one year of age, according to BetterVet. Transition them gradually under the guidance of your veterinarian. Cats and kittens have different caloric needs. Your furry kitten ball is still undergoing changes and rapidly growing, so they need a special diet before they reach adulthood. 

Is your kitten ready to transition to adult cat food? Look for signs like steady growth, a shift in activity levels, and changes in appetite. Consult your vet if you’re unsure; they can recommend the best feeding plan based on your kitten’s breed, size, and health.  

Making the switch to adult cat food isn’t complicated if you keep track of your pet’s age:

• First stage: Kittens, like toddlers, go through a weaning phase but  usually, with far less mess and tantrums. Around 5–6 weeks of age, kittens naturally start exploring solid food. During this period, they’re still nursing or bottle-fed, but they’re ready to dip their tiny paws into something more substantial.  
• Second stage: By 7–8 weeks, most kittens are ready for an all-solid diet. This transition is gradual and often led by their mother, who might subtly encourage independence by spending less time nursing. If your kitten is bottle-fed, you can mirror this process by reducing formula feeds and increasing solid food availability.  
• Third stage: By one year, kittens can gradually be introduced to adult cat food. You can choose either wet or dry cat food as long as they offer appropriate nutrients to your fur baby.

Why You Should Transition Kittens to Adult Cat Food at the Right Time

Kitten food isn’t just “cat food for tiny cats.” It’s a supercharged blend designed to meet their unique nutritional needs. Dr. Jennifer Larsen, DVM on WebMD says that kittens need significantly more energy than adult cats. They’re such a bundle of kitten zoomies that they need up to triple the energy requirements. Their growing bodies demand higher levels of protein (about 30% of their energy), amino acids, minerals, fat, and certain vitamins.

Think of kitten food as the fuel for their growth spurts, playful antics, and relentless curiosity. Transitioning too early to adult cat food deprives them of these essential nutrients, potentially impacting their development.  

Wet or Dry: Which is Better for Your Kitten?  

When it comes to the wet-versus-dry food debate, kittens might not have a preference, but you should. Here’s a quick rundown of the pros and cons of each:  

Wet Food:  

• Easier to eat for tiny teeth 
• High moisture content keeps kittens hydrated  
• Easy to mix in supplements like probiotics  

Dry Food:  

• Supports dental health by reducing plaque buildup 
• Convenient for free-feeding
• Cost-effective for budget-conscious pet parents

For very young kittens, wet food is non-negotiable because they simply can’t chew kibble effectively. Make sure to choose a brand with the best wet cat food ingredients. Over time, offering both wet and dry options helps create a flexible eater who’s less likely to turn up their nose at future meals.  You might also be wondering, is it okay to mix wet and dry cat food? Yes, as long as you’re mindful of the portions and the nutritional content of the cat food.

Selecting the Right Kitten Food  

Not all kitten foods are created equal. If US food brands are available in your pet store, look for a label stating the food meets the AAFCO nutritional standards for kittens. Ideally, it should also mention “complete and balanced nutrition” based on feeding trials, which ensures your kitten gets all the necessary nutrients without needing supplements (unless prescribed by your vet).  

Generic or store brands may be cheaper, but these may lack rigorous testing or nutritional quality. To make sure, always check the label for ingredients and breakdown of nutrients. Remember, a good diet results in a kitten who’s healthy, alert, and sporting a shiny, sleek coat.

Breed Matters When Transitioning Kittens to Adult Cat Food

Most experts agree: kittens should stay on kitten food until they reach 12 months of age. This timeline aligns with their developmental milestones and nutritional needs. However, there are exceptions:  

• Large Breeds (e.g., Maine Coons, Bengal, Ragdoll, Persian, or Siberian) - These gentle giants grow more slowly and may need kitten food longer since they reach adulthood between 18–24 months.  For instance, Dr. Elizabeth from Boop by PetCo says purebred Main Coons should be fed kitten food until 15 months since they’re still growing.
• Spayed/Neutered Cats - These cats may have lower energy needs, so consult your vet about their diet.

Transitioning Your Kitten to Adult Cat Food

When it’s time to transition to adult cat food, do so gradually over  7–10 days to avoid upsetting their stomach. Mix small amounts of the new food with their kitten food, increasing the ratio until they’re fully switched over.  

How Much and How Often Should You Feed a Kitten?

Kittens are snackers, not feasters. Their small stomachs mean they can’t pack in enough calories in one sitting. Here’s a general guide:  

• Under 6 months: Feed 3–4 small meals a day or allow free-feeding with dry food.  
• 6–12 months: Transition to 2 meals a day as their growth slows.  

Free-feeding can be beneficial for underweight kittens but isn’t ideal for those prone to overeating or obesity. Portion control becomes especially important around the time of spaying/neutering, as these procedures increase the risk of weight gain.  

Food to Avoid for Kittens

While kittens might beg for a bite of your sandwich, some foods are strictly off-limits:  

• Raw meat, liver, or eggs— Risk of harmful bacteria and nutrient imbalances.  
• Milk—Contrary to popular belief, most kittens are lactose intolerant.  
• Onions, garlic, chocolate, grapes, and raisins—Toxic to cats, even in small amounts.  

Treats should make up less than 10% of their daily calorie intake, and table scraps should be avoided altogether.  

Switch From Kitten to Adult Cat food at the Right Time 

Feeding your kitten right sets the stage for a healthy, happy life. Kittenhood may be fleeting, but the memories of their tiny antics and bottomless appetite will last a lifetime. With the right food, plenty of love, and a pinch of patience, your kitten will thrive and reward you with a lifetime of purrs.
