Kitten feeding and nutrition guide
The first few months of your kitten’s life will consist of rapid growth, discoveries, and various developments. Therefore, knowing what to feed your kitten from the beginning is vital to supporting healthy growth. As their bones grow and their brain matures, they will require energy, protein, and other nutrients. Choosing a diet that provides the right balance will set your kitten up for a long and healthy life.
How kitten feeding differs to adults
Kittens' nutritional needs are very different from those of adult cats. Their food should contain more energy and protein than adult cat food to support bone and muscle growth. As they explore, play, and grow, kittens need food adapted to their size while providing the right balance of nutrients to support their development.
feeding your kitten through each stage of life
The importance of diet
Your kitten’s food must be up to the task of supporting their development as they go through intense periods of growth. It should be easy on the digestive system and suited to their mouth and teeth. Kittens require a diet high in protein to support the growth of their skeleton and muscle.

What does healthy development look like?
For all kittens, the pace of growth is intense in the first months of life, but that growth differs from one breed to another. Most cats will reach adulthood between 12 and 15 months of age. But the tiny Singapura (the smallest recognized breed of cat) won’t have the same nutritional requirements at the same stage as their more imposing Maine C**n or Persian cousins. It’s important to consult a chart that gives kitten feeding guidance by age and breed and it’s a good idea to speak to your vet for advice tailored to your cat. That way you can be sure your kitten’s food is giving them the right support for their rapid development.

Birth to 4 months
At this early age, your kitten is growing at a lightning-fast pace. A week-old kitten has only just opened their eyes. Fueled by their mother’s colostrum, which builds their immunity, and then by milk, they gain around 0.3-1 oz of weight per day. Fast forward to a month old and that tiny bundle has already transformed into an inquisitive and playful, though still small, explorer. They’ll be ready to start weaning—a vital process as the kitten transitions from complete dependence on their mother for their nutritional needs, to independence. The weaning process is usually completed at around two months. Their first food needs to be soft, to ease the transition from milk to solid food, and full of the antioxidants they need to build their immunity, as well as amino acids to aid muscle and cell growth.
Feeding kittens wet versus dry food
Feeding your cat wet food rather than dry food has its benefits, as it not only contributes to their water intake but also has a stronger aroma that may tempt them if they are a fussy eater. This is due to a cat’s sense of smell being more sensitive than their taste. On the other hand, dry food is better suited for grazers, as it stays fresher in their bowl for longer.
However, we encourage pet owners to mix-feed by incorporating both wet and dry food into their kitten’s diet.
Managing the transition
Either way, you should gradually introduce changes to your cat’s diet to prevent stomach upset. Cats can be sensitive to changes in their diet, and a slow transition (done over 7 days) will help avoid any issues.
Kittens normally drink their mother’s milk in their first weeks of life, so a replacement milk specially formulated for kittens can play an important nutritional role if the mother’s milk isn’t possible.
However, kittens should not be given cow’s or goat’s milk (neither should adult cats) as this can be difficult for them to digest properly, which can cause diarrhea.
Kittens and cats are sensitive to change in their diet and require a slow transition to avoid any problems.
What should you feed your kitten?
One of the big questions you’ll ask yourself as a new pet owner will be what to feed your kitten. Wet food contributes to your cat’s water intake and has a strong aroma that may tempt fussy eaters to go to their bowl. Cats are more sensitive to smell than they are to taste. On the other hand, dry food stays fresher in the bowl for longer—good news for grazers, which cats are by instinct.
Kibble’s texture has another benefit for your cat
It acts in much the same way as a toothbrush, gently removing tartar. As to when your kitten can eat dry food, tiny rehydratable kibble designed for kittens is suitable from one month of age, around when the weaning process begins. Once you’ve done your research, you may conclude that a mix is the ideal solution, either alternating dry and wet food or feeding a little of both at the same time (but not in the same bowl–the wet food will turn the dry kibble soggy if your cat doesn’t eat it all straightaway).
