How Much to Feed a Senior Cat: Portion Guide
How much to feed a senior cat, with calorie targets, wet and dry portions, meal frequency, and body condition tips. Use our food calculator for a personalized amount.
Figuring out how much to feed a senior cat sounds simple until you stare at the feeding chart on the bag and realize it barely accounts for your individual cat. Portion needs change as cats age, and they change in different directions depending on the cat. The number on the package is a starting point, not a prescription.
This guide gives you practical calorie targets, shows how those translate into wet and dry portions, and explains how to read your cat's body to fine-tune. For a personalized estimate based on your cat's weight and condition, try our cat food calculator, then use the principles below to adjust.
Start With a Calorie Estimate
A reasonable baseline for a healthy senior cat is roughly 18 to 22 calories per pound of ideal body weight per day. For a lean 10-pound cat, that lands around 180 to 220 calories daily. A smaller 8-pound cat might need closer to 150 to 175, while a larger or more active cat needs more. These are starting figures from maintenance energy estimates, not exact requirements, and your cat's real needs may sit above or below the range.
The key phrase is ideal body weight. If your cat is overweight, calculate from the weight they should be, not the weight they are, so you are feeding toward a healthy target rather than maintaining excess fat.
Translate Calories Into Real Portions
Calories only help once you connect them to food in the bowl. The catch is that calorie density varies enormously between products, so you have to check the label on your specific food.
- Wet food: A 3-ounce pate can typically holds 70 to 100 calories. A 10-pound cat needing about 200 calories often eats two to three of these a day.
- Dry food: Kibble is far more calorie-dense, commonly 300 to 500 calories per cup, so the same calories take up a small fraction of the volume. This is exactly why it is so easy to overfeed dry food by eye.
- Mixed feeding: If you feed both, count the calories from each and add them together rather than feeding a full portion of each.
Because eyeballing kibble leads to overfeeding, a simple kitchen or pet food scale and a consistent measuring scoop are worth the small investment. Measuring by weight is more accurate than measuring by a scooped cup.

Body Condition Beats the Bowl
Numbers get you in the neighborhood, but your cat's body tells you whether you are right. The body condition score is the single best feeding feedback you have. Run your hands along your cat's sides: you should feel the ribs easily under a thin layer of fat, not see them poking out and not have to press through a cushion of fat to find them. From above, a slight waist should be visible behind the rib cage. From the side, the belly should tuck up rather than sag.
If your cat is developing a hanging fat pad and losing the waist, ease portions down. If the spine, hips, and ribs are becoming sharp and prominent, increase calories and, importantly, see your vet, because weight loss in an older cat is often a medical sign rather than a feeding shortfall.
Meal Frequency for Older Cats
Senior cats generally do better with two to four smaller meals a day than with one or two large ones. Smaller, more frequent meals match a cat's natural inclination to eat many tiny meals, are easier on aging digestion, and keep energy steadier. Frequent small servings also help cats with reduced appetite take in more over the course of a day. If your schedule makes midday meals hard, an automatic feeder can cover them, though wet food needs a chilled or timed feeder to stay safe.
How Aging Shifts the Numbers
There is no single senior portion because aging pulls cats in two directions. In the early senior years, around 11 to 13, many cats become less active and their metabolism slows, so they need slightly fewer calories and are prone to weight gain. Later, often past 13 or 14, the trend reverses: cats start losing muscle and digesting food less efficiently, so they may need more calories and more frequent, calorie-dense meals just to hold their weight. Reassess portions a few times a year rather than setting them once.

Measure, Track, and Adjust
The most useful habit you can build is measuring meals and tracking your cat's weight. Measured meals, rather than free-feeding, let you see exactly how much your cat eats, which means a drop in appetite, one of the earliest signs of illness in seniors, becomes obvious instead of hidden. Weigh your cat every few weeks on a kitchen or baby scale, note the trend, and adjust portions gradually. Sudden changes in either direction are a reason to involve your veterinarian.
The Bottom Line
How much to feed your senior cat starts with a calorie estimate of roughly 18 to 22 calories per pound of ideal weight, translated into measured wet or dry portions using your food's actual calorie content. From there, let body condition and weight trends do the fine-tuning, feed two to four small meals a day, and reassess as your cat ages, since needs change over time. Use our food calculator for a personalized starting point, then watch your cat, not just the bag.

Frequently Asked Questions
How many calories does a senior cat need per day?
A rough starting point is about 18 to 22 calories per pound of healthy body weight per day, so a lean 10-pound senior cat needs roughly 180 to 220 calories. This is only a baseline. Activity level, body condition, and health conditions shift the number, and the most reliable guide is whether your cat is holding a healthy weight over time. Our food calculator gives a personalized estimate.
How much wet food is that in cans?
Most 3-ounce pate cans contain roughly 70 to 100 calories, so a 10-pound cat needing about 200 calories a day often eats around two to three cans, split into meals. Calorie content varies widely between brands, so check the kcal listed on your specific can rather than assuming. Dry food is more calorie-dense, so the same calories take up far less volume.
Should I feed my senior cat more or less than when they were younger?
It depends on the cat. Younger seniors often need slightly fewer calories as activity drops and can gain weight, while cats in their late teens frequently need more calories and more frequent meals as they lose muscle and digest less efficiently. There is no single answer, which is why watching body condition matters more than following one fixed number.
How many meals a day should an older cat have?
Two to four smaller meals a day usually suits senior cats better than one or two large ones. Smaller, frequent meals are gentler on digestion, match a cat's natural grazing pattern, and help maintain steady energy. For cats with reduced appetite or certain health conditions, more frequent small meals can also encourage better overall intake.
How do I know if I'm feeding the right amount?
Use body condition, not the bowl. Run your hands over your cat: you should feel the ribs under a thin layer of fat without seeing them, and see a slight waist from above. If your cat is gaining a fat pad or losing definition over the spine and hips, adjust portions and talk to your vet. Weigh your cat regularly to catch trends early.
Should I free-feed or use measured meals for a senior cat?
Measured meals are generally better for older cats. Free-feeding kibble makes it easy to overfeed and impossible to notice when appetite drops, which is an important early warning in seniors. Measured portions let you track exactly how much your cat eats each day, so a change in intake is visible right away and you can act on it quickly.
My senior cat is losing weight even though I feed plenty. Why?
Unexplained weight loss despite eating well is a classic sign of hyperthyroidism, and it can also signal diabetes, kidney disease, or malabsorption. It is not a portion problem you can simply feed your way out of. Schedule a veterinary exam with bloodwork. Once any condition is identified and treated, feeding adjustments become much more effective.
