Indoor cats burn fewer calories and cough up more hairballs. Here's how the right dry food helps, plus our picks.
What makes an indoor formula different
Indoor cats move less than outdoor hunters, so weight gain is a real risk. Indoor formulas are typically lower in calories and higher in fiber to promote fullness and help move swallowed hair through the gut, reducing hairballs. They still need quality animal protein to preserve lean muscle. The aim is a food that satisfies a housebound cat without the excess calories that quietly lead to obesity and its downstream health problems.

Our indoor dry-food picks
[Hill's Science Diet Indoor Adult Cat Food](/products/hills-science-diet-indoor-adult-cat-food) is formulated for lower activity with fiber for hairball control and digestible ingredients. [Purina ONE Indoor Advantage Dry Cat Food](/products/purina-one-indoor-advantage-dry-cat-food) offers real-turkey protein, weight-conscious calories, and hairball support at an accessible price. Both are complete and balanced for adult maintenance, making them solid everyday staples. If your cat also has a touchy gut, a sensitive-stomach recipe may suit better.
When digestion is also a concern
Some indoor cats combine low activity with a sensitive stomach or itchy skin. [Hill's Science Diet Adult Sensitive Stomach & Skin Dry Cat Food](/products/hills-science-diet-adult-sensitive-stomach-skin-dry-cat-food) targets easy digestibility and skin support while still working for indoor life. Whatever you pick, portion by the bag's guidelines for your cat's ideal weight — not free-feeding — since leaving a full bowl out all day is a leading cause of indoor-cat weight creep.
Keep indoor cats lean and hydrated
Dry food is convenient and good for dental-friendly crunch, but it's low in moisture. Pair it with a wet meal, a water fountain, or multiple water stations to support urinary health. Measure portions, weigh your cat periodically, and adjust as needed — you should be able to feel the ribs without pressing hard. Enrichment like play and food puzzles burns calories and eases boredom eating. If your cat gains despite careful feeding, ask your vet to check for underlying causes.

Frequently asked
- Do indoor cats really need special food?
- Not strictly, but indoor formulas help by controlling calories and adding hairball-managing fiber for less-active cats. The bigger factor is portion control — any quality food overfed will still cause weight gain.
- How do I stop my indoor cat gaining weight?
- Measure meals instead of free-feeding, choose a calorie-appropriate food, add play and food puzzles for activity, and weigh your cat regularly. If weight climbs despite this, check with your vet.
