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 in 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.

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 Coon 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.

4 to 12 months
Your kitten’s growth is continuing and they are developing strong muscles and bones. Growth is at its most intense at around four or five months, when your kitten could be gaining around 3.5oz a week. They need a more energy-dense food—a food that contains more calories per ounce—than adult cats. But at first, it must be one that little mouths can still manage while they’re waiting for their adult teeth to grow in. Keep a close eye on portion sizes to ensure your kitten does not put on too much weight during this growth phase. At this age, kittens are busy playing and also honing their social skills. During this period your cat will go through puberty and you may notice that they start to behave more like an adult cat. That could include sleeping for as much as 13 to 16 hours a day. After all, growing, developing and socializing is tiring work.
