Our #1 indoor cat food
Advance
Best for indoor cats · $$$
The best all-round value in our cat index — Aussie-made, vet-recommended and with a formula for almost every life stage. Comfortably our recommendation for most households.
Indoor cats simply burn less than outdoor cats do. Feed a standard formula at the same rate and the weight tends to creep up over time.
More grooming and no grass to nibble means more hairballs. Indoor formulas lean on specific fibres to move hair through the digestive tract.
A quieter, less active life can play into urinary troubles. More moisture, whether from wet food or an indoor-formula dry, helps support the urinary tract.
Some indoor formulas add nutrients like L-tryptophan or certain B vitamins, linked to calmer behaviour in cats that don't have much to do.
An indoor cat that puts on weight faces higher odds of diabetes and joint trouble. A controlled-calorie formula is worth thinking about from middle age.
Whatever you feed, getting the portions right matters most. Indoor cats aren't great at self-rationing when free-fed, so measure meals and follow the pack guide.
Ranked on weight-management formulation, hairball control, ingredient quality and how easily you'll find them in Australia.
Advance's Indoor Adult range is one of the best-value indoor formulas in Australia. It's Australian-made, vet-recommended, and built around the two things that matter most for a stay-at-home cat: keeping weight in check and helping hairballs on their way.
Hill's Science Diet Indoor has decades of nutritional research behind it and a lot of vets who trust it. It uses controlled calorie density and added fibre to hold weight steady and ease hairballs through the digestive tract.
Black Hawk's grain-free dry range runs lower in carbs, which helps a sofa-loving indoor cat stay lean. It's Australian-owned and sensibly priced — a dependable pick if you want grain-free without paying import prices.
Royal Canin Indoor formulas are made for exactly this life: a precise calorie level to keep weight gain at bay, hairball-reducing fibre, and enrichment nutrients to support mental wellbeing. The science is thorough, though you do pay a bit more for it.
Ivory Coat's grain-free recipes sit lower in carbs than most supermarket dry foods, which helps a less-active cat hold a healthy weight. Australian-made and clean-labelled, it's a strong everyday choice.

Not really. Any good complete-and-balanced cat food can do the job. But indoor formulas are tuned for a less active life: fewer calories, often extra fibre for hairballs, and sometimes enrichment nutrients to make up for less going on around the house. They're worth a look if your cat is putting on weight or bringing up hairballs a lot.
Indoor cats tend to groom more, often out of boredom or habit, and they miss out on grass — which outdoor cats nibble partly to help shift hair through the gut. A hairball-formula diet uses specific fibres (often psyllium, cellulose or beet pulp) to move swallowed hair through more smoothly.
Looking down from above, a healthy cat has a visible waist, and you should be able to feel their ribs with light pressure without seeing them. If that waist has vanished or the belly's looking round, the weight may be creeping up. Your vet can check their body condition score at a routine visit.
Wet food brings more moisture, which is good for hydration and urinary health — a real plus for cats that aren't big drinkers. Dry food packs more calories per bite, so portions matter more. Lots of indoor cat owners simply do both: dry for convenience, and a wet meal once or twice a day for hydration and a bit of variety.
No. Pet Reviews is an independent comparison resource, and this isn't veterinary advice. If your cat is carrying a lot of extra weight or has a health condition, please consult your vet before changing their diet.
