Purina One Indoor Advantage is a chicken-based dry kibble formulated for adult cats living primarily indoors. The 2.8kg pack targets the specific issues indoor cats deal with — lower activity levels, more grooming, and the hairballs that come with it — rather than a generic adult formula.

The recipe leads with real chicken and includes a natural fibre blend to help move swallowed hair through the digestive tract rather than back up onto the carpet. Purina's Immune Defence Plus+ adds beta glucans, vitamins C and E as antioxidants, and omega 3 and 6 fatty acids to support skin and coat condition. Calorie density is pitched at indoor activity levels to help maintain a healthy weight without portion-cutting.

This suits owners of housebound cats who want a mainstream, widely stocked formula that addresses hairballs and weight management without stepping up to a prescription diet. The chicken flavour tends to be accepted by fussy eaters, which matters more with indoor cats that can afford to skip meals.
