Hill's Science Diet Indoor Cat Food

Hill's Science Diet Indoor cat food is built for cats that live entirely inside — five recipes covering kitten through to the late senior years, in dry and wet.

An indoor cat has a different problem set to one that goes out. Activity is lower, so kilojoules have to come down or weight creeps on. All the grooming happens indoors, which means more swallowed fur, so the formula leans on natural fibres to move hair through the gut rather than back up onto the carpet. The same fibre blend is aimed at stool volume and litter tray odour, which matters a great deal more when the tray sits in your living space.

The genuinely useful thing about this range is how finely Hill's splits the age bands. Most brands offer an indoor kitten, an indoor adult and a single senior formula. Hill's runs Indoor Kitten, Adult Indoor, then Adult 7+ Senior Indoor and Adult 11+ Senior Indoor — two separate senior stages. An eleven-year-old cat has different kidney, heart and muscle needs to a seven-year-old, and this is one of the few ranges that lets you feed for that difference instead of lumping every cat over seven into one bag.

The fifth product is the Adult Indoor Savory Chicken Entree wet food. Indoor cats often drink too little, so a tin alongside the dry kibble is a practical way to lift water intake without leaving the formula.

Pick by age first, then decide dry, wet or both. If your cat sits between stages — say, ten years old and in good health — stay on the 7+ formula until your vet gives you a reason to move up, rather than jumping to 11+ early.
