An indoor cat burns 20–30% fewer calories than an outdoor cat of the same weight. Standard adult formula at the standard portion = creeping weight gain. Indoor-formula food fixes this with three changes: lower fat, higher fibre (for hairball management), and L-carnitine for fat metabolism. Most AU indoor cats benefit measurably.
If your indoor cat is even mildly overweight, switching to a properly-formulated indoor food costs nothing extra and visibly reduces hairballs within 4–6 weeks.
Hill's Science Diet Adult Indoor
Reduced calories vs standard adult, added L-carnitine, natural fibre for hairball control. Widely stocked.
Best for: Most indoor adult cats 1–7 years old.
Royal Canin Indoor 27
Higher fibre (12%) for hairball + stool odour management. L-carnitine for weight control. Slightly more expensive than Hill's equivalent.
Best for: Indoor cats with sensitive digestion.
Advance Indoor Adult Chicken
Aussie-made, vet-recommended. Marginally lower fibre than RC Indoor 27 but still effective on hairballs.
Best for: Indoor cats and budget-aware owners wanting AU manufacture.
Black Hawk Indoor Adult Chicken & Rice
Higher meat content than Advance Indoor. No artificial preservatives.
Best for: Owners wanting Australian-made without 'prescription' branding.
Fancy Feast Classic Pâté (alongside any indoor dry)
Cheap enough to feed daily, hydrates the cat, and lowers urinary-tract risk that indoor cats are mildly more prone to (less water-seeking behaviour than outdoor cats).
Best for: Any indoor cat — daily wet meal alongside dry kibble.
Frequently asked questions
Do indoor cats really need different food?
Yes if they're putting on weight, having hairball issues, or producing high-odour stool. No if they're at a healthy weight and the standard formula works. The marketing oversells the necessity — but the underlying formulation differences are real.
How much should I feed an indoor cat?
Around 20–30% less than an outdoor cat of the same weight. Our cat food cost calculator at /tools/cat-food-cost-calculator does the maths for you.
Will indoor food fix my cat's weight problem alone?
Helps but isn't enough. Most weight problems are portion problems first, food-choice problems second. Measure portions with a scale, not a cup. Indoor formula buys you ~5–10% on top of that.
