Hill's Adult Cat Food

Hill's Adult Cat foods are the Hill's variants aimed at adult cats in the prime of life, all developed to keep your cat feeling young and lively for as long as possible.

Hill's Adult cat foods are included in both the Hill's Science Plan range and Hill's Nature's Best range. They also include Hill's Science Plan Adult Light variants for less active and overweight cats plus variants for combating certain health issues in cats such as sensitive skin, hairballs and sensitive digestion.
