Hill's Science Diet Perfect Digestion is a dry cat food for adult cats aged 1 to 6, built around a chicken, barley, and whole oats recipe specifically developed to support digestive health and gut microbiome balance.

The formula features Hill's ActivBiome+ blend — a proprietary combination of prebiotics designed to nourish the gut microbiome rather than simply add fibre. Whole grain oats and pumpkin contribute additional digestive support. Chicken is the primary protein, and the kibble delivers the balanced nutrition expected from the Science Diet range. It targets cats whose digestion is sensitive or unpredictable rather than those with diagnosed conditions.

Owners typically choose this when a cat has ongoing loose stools or variable digestion that doesn't warrant a prescription diet — a step up from standard adult foods that addresses gut health without requiring a vet referral.
