Dry Cat Food

Kitten food is calorie-dense and built to support rapid early growth, and should not be swapped for an adult formula before your kitten is developmentally ready — check the age guidance on the bag rather than guessing from size alone.

Senior cat food, like Purina One Senior 7+ Bifensis Chicken, is generally adjusted for a lower activity level and often supports joint or kidney health, which becomes more relevant as cats age.

James Wellbeloved Light Adult Dry Cat Food Fish and Go Cat Herring with Vegetables both sit in the everyday adult range, and the difference between fish and other proteins usually comes down to what your own cat prefers or tolerates rather than one being objectively better.

A 'light' formula is worth considering for an indoor or less active cat that is prone to putting on weight, rather than assuming every adult cat needs the same calorie density.

Move a kitten onto adult food gradually once they reach the age stated on the packaging, mixing the new food in over about a week rather than swapping overnight.

The same gradual approach applies moving an adult cat onto a senior formula — there is no need to switch suddenly at a specific birthday, and most owners find it easier to start the transition when they notice a change in activity or weight.
