Every cat is a true individual, with a personality and a set of nutritional requirements all their own. While deciding what food to feed can feel like a maze, selecting the right fuel is one of the most impactful decisions a pet parent can make. From the high-energy needs of a playful kitten to the specialised support required by a sophisticated senior, tailored scientific nutrition offers a precise balance of nutrients. By matching a diet to a cat's specific life stage, breed, and lifestyle, it is possible to support long-term health and keep those purrs coming for years to come.
The right food for your cat depends on their life stage, breed and lifestyle. Kittens need a growth diet until around 12 months, adult cats do best on a balanced maintenance diet, and mature and senior cats benefit from food that helps them keep lean muscle and a healthy weight. Breed and indoor diets then fine-tune things further. Below, we walk through each stage and link to our detailed guides.
What does my cat need at each life stage?
A cat's nutritional needs will change over the course of their life. There are a number of different life stage scales identified for cats, which are predominantly based on their age however it is important to note that these are designed to be a starting point only, and it is best to consult a veterinarian regarding your cat's specific needs. For a look at life stage feeding across all pets, see our guides to age-appropriate food and when to change pet food for life stage.
Kitten (up to 12 months)
Kittens need precisely balanced nutrition to support their growth and development, including higher levels of energy, adapted protein and the right levels of vitamins and minerals such calcium and vitamin D.
For portion sizes, see how much to feed a kitten, and for food options, our guide to the best kitten food.
Young adult (1 to 6 years)
Energy requirements in young adult cats will be lower than growing kittens and is dependent on a number of factors including neuter status and activity levels. If active, young adult cats can have higher nutritional requirements for energy compared to senior cats.

Mature adult (7 to 11 years)
As cats become more mature, their energy requirements may reduce, although it is important to make adjustments based on their individual needs. Healthy mature adult cats also may need higher levels of protein to maintain lean muscle mass. Water intake should also be considered to help support urinary health, including some wet food in the diet may help with this.
Our guides to wet vs dry food for cats and how to increase your cat's water intake can help.
Senior (over 11 years)
The ability of cats to effectively and efficiently digest their food can reduce with age, which in turn can mean they need to eat more calories to maintain their body condition. They may also have reduced appetite, so changes to their food to make it more appealing and easier to eat can also be beneficial.
Our best senior cat food guide is a good next step.
At what age is a cat a senior?
Most cats are considered mature from around 7 years and senior from around 11, but every cat ages a little differently, so treat these ages as a starting point rather than a rule.
Vets watch weight, coat condition, mobility and energy levels, rather than going on the birthday alone. If you've noticed your cat slowing down or changing their eating habits, it's worth a chat with your vet about whether a mature or senior diet is the right move.
Why do indoor cats need different food?
Typically indoor cats are less active than those that have access to the outdoors. This can mean that they have lower energy requirements and may benefit from being fed a diet with an adapted fat and energy content. Indoor cats also will use a litter tray exclusively when they need to toilet, so many indoor cat foods contain specific nutrients such as prebiotic fibres to help reduce stool odour.
Feeding your cat a tailored diet specific to their age and other factors such as breed and lifestyle is one way you can help to keep them happy and healthy. Tailored cat foods may also help to avoid commonly occurring health problems, particularly obesity which can in turn predispose to other chronic health conditions including diabetes, mobility issues and urinary tract disease.

Do some cats need a breed-specific diet?
Breed specific cat foods are tailored specifically to address common health issues and preferences among particular breeds of cats. For example, Royal Canin Adult Ragdoll and Royal Canin Maine Coon foods are enriched with nutrients like taurine and omega 3 fatty acids to support healthy cardiac function, because these breeds can be predisposed to heart problems. They also have a specialised kibble shape and texture to suit the jaw and chewing style of each breed.
If you share your home with one of these breeds, our guides to the best cat food for Ragdolls and the best cat food for Maine Coons cover what to look for.
