Dry Food for Indoor Cats: What to Look For

The feeding guide printed on a bag of dry cat food is an average, and an indoor cat is rarely average. A cat that spends most of the day on a sofa burns fewer calories than one patrolling gardens, and kibble packs a lot of energy into a small scoop. So the useful questions about dry food for an indoor cat have less to do with brand than with amount, composition and what else goes in the bowl.
The scoop is where indoor cats go wrong
Weight gain is the usual indoor-cat problem, and it tends to creep. Neutered cats generally need less energy than entire ones, and a cat with no hunting or climbing outlets needs less again. Dry food makes overfeeding easy because a heaped scoop looks small and the bowl can sit full all day.
Three habits help.
- Weigh the food. Kitchen scales are more reliable than a scoop, which can vary by a fair margin from one pour to the next.
- Feed to the weight she should be, not the weight she is. The feeding table on the bag is usually organised by body weight. If your cat is carrying extra, ask the vet or practice nurse what a healthy target is.
- Count everything else. Treats, dental snacks and licks of wet food all add up.
You can check body condition at home. From above, a healthy cat has a visible waist. From the side, her belly should tuck up slightly, and you should be able to feel her ribs under a thin covering of flesh without pressing hard. If you can't, it is worth a conversation with the vet, because rapid weight loss in cats can itself be risky and is best supervised.
Six label checks that take a minute
| Check | What it tells you |
|---|---|
| "Complete" or "complementary" | Complete food is meant to be the whole diet. Complementary food isn't, and shouldn't be the main bowl. |
| Life stage | Adult, senior and kitten foods are balanced differently. Kitten recipes are richer and not designed for a sedentary adult. |
| What the meat actually is | "Chicken" tells you something. "Meat and animal derivatives" is a broad category. Cats are obligate carnivores, so animal-sourced protein matters. |
| Ingredient order | Ingredients are listed by weight as used. Fresh meat is heavy before cooking removes the water, so a high position can overstate how much remains in the finished kibble. |
| Analytical constituents | Protein, fat, fibre and ash percentages let you compare like with like between dry foods. |
| Energy per 100g | This lets you work out what a portion really delivers. If a brand doesn't state it, portioning is guesswork. |
What "indoor" on the front of the bag means
It is a marketing label, not a defined standard. Foods sold as "indoor" typically adjust energy, fibre or both, and often make hairball claims. Treat those as claims: fibre is said to help hair pass through, but regular brushing is the more direct way to cut down on swallowed hair. More important than the word on the front is the analysis on the back, and whether the amount you pour matches your cat's needs. Foods marketed for weight control exist, but for a cat that is already overweight, a vet-led plan is safer than picking one yourself.
Water: the part dry food can't supply
Dry food is low in moisture, while wet food is mostly water, so a cat eating only kibble has to drink more to compensate. Cats are often said to have a modest thirst drive, and many drink less than their owners would like. Several things help:
- put more than one bowl down, away from the food and, importantly, away from the litter tray;
- try wide, shallow bowls or a drinking fountain, which some cats prefer;
- add a little water to food, if she accepts it.
Adding some wet food is the simplest route. Our guide to wet versus dry cat food covers how to split the two without overshooting calories. If your cat suddenly starts drinking much more than normal, that is a reason to ring the vet, not a sign she is simply thirsty. This is general information, not a diagnosis.
Making the bowl do more
Indoor cats eat out of boredom as often as hunger. Splitting the day's portion into several small meals, using a puzzle feeder, or scattering a few kibbles around the room gives her something to do and slows the speed at which food disappears. If the stomach reacts badly to a new food, switch gradually over at least a week or so; the plan in our guide for cats with sensitive stomachs works for any change.
One more point: don't feed a kitten on adult indoor food to save money or hassle. Growing cats have different needs, and our kitten food guide explains what to look for until she is fully grown.
In short, pick a complete adult food whose label you can read, weigh the portions against the weight your cat should be, and give her some water-rich food and plenty of drinking spots. Anything marketed specifically for indoor cats is a bonus, not a substitute for those basics.
