A cat’s nutritional needs change dramatically from the rapid growth of kittenhood to the slower metabolism of old age. Feeding a six-week-old kitten the same way you feed a twelve-year-old cat is a recipe for either stunted growth or creeping obesity. This guide breaks feeding down by life stage — how much, how often, and how to transition safely — using guidance from the AVMA, the Cornell Feline Health Center and the ASPCA.
One rule cuts across every age: feed measured portions, not a bottomless bowl. Free-feeding dry food is the single most common cause of the overweight cats veterinarians see every day. A consistent feeding routine also pairs beautifully with training — mealtimes are natural moments to reinforce good behavior, as we cover in our cat training tips.
How needs change with age
The three broad life stages are growth (kitten), maintenance (adult) and senior. Here is how energy needs and meal frequency shift across them:
Feeding kittens (0–12 months)
Kittens are tiny growth engines. Pound for pound they need roughly two to three times the calories of an adult cat, and they need it in small, frequent doses because their stomachs are small. Always feed a food labelled for “growth” or “kitten,” or one labelled for all life stages — the AVMA recommends choosing a complete and balanced diet appropriate to the life stage.
- Under 6 months: three to four small meals daily. Newly weaned kittens may need food left out a little longer since they eat in tiny amounts.
- 6–12 months: two to three meals daily as the stomach grows and appetite settles.
- Portion: follow the kitten food label as a starting point, then adjust so ribs are easy to feel but not see and the kitten stays lively and steadily growing.
Resist the urge to overfeed a chubby kitten “because they’re growing.” Steady, lean growth is healthier than rapid weight gain. For figuring out exact daily calories, see our companion guide on how much to feed a cat.
Feeding adult cats (1–7 years)
Once growth is complete, the goal shifts from building a body to maintaining one. Most adult cats do very well on two measured meals a day, morning and evening. Cats are natural grazers in the wild — eating many small prey-sized meals — so some owners split the daily ration into several tiny portions or use a timed feeder, which can curb begging and obesity.
Keep fresh water available at all times. Cats evolved from desert animals and have a low thirst drive, so encouraging water intake — through wet food or water fountains — supports urinary health. We compare the trade-offs in detail in our guide to wet vs dry cat food.
Feeding senior cats (7+ years)
There is no single “senior diet” that suits every older cat. The Cornell Feline Health Center emphasizes that aging cats vary enormously: some lose weight and muscle and need more easily digestible calories, while others slow down and gain weight. Common adjustments your veterinarian might recommend include:
- Kidney-supportive diets for cats with declining renal function, a frequent issue in older cats.
- Softer or wet food when dental disease makes crunching kibble painful.
- Calorie tuning up or down depending on whether the cat is losing muscle or gaining fat.
This is why regular wellness exams matter more as cats age — feeding should follow the cat’s health, not a number on the calendar. A sudden change in appetite, weight or thirst always warrants a vet visit rather than a DIY diet change.
How to transition foods safely
Whether you’re moving a kitten onto adult food, switching brands, or starting a vet-recommended senior diet, change should be gradual. Cats are notoriously sensitive to abrupt diet changes, which can trigger stomach upset or outright refusal. A simple seven-to-ten-day schedule works well:
- Days 1–3Feed about three-quarters old food, one-quarter new food, mixed together.
- Days 4–6Move to a half-and-half blend of old and new.
- Days 7–9Shift to one-quarter old, three-quarters new.
- Day 10Feed the new food entirely, watching that stools and appetite stay normal.
If your cat develops loose stools or refuses to eat, slow the transition down and give it more days at each stage. Picky eaters often need extra patience, much like the patience that pays off in training a cat any new behavior. You can even track feeding milestones alongside training goals in our free progress tracker.
Building a feeding routine that lasts
Across every life stage, the cats that stay healthiest tend to live on a predictable schedule. Cats are creatures of habit, and regular mealtimes reduce the anxious begging and food-guarding that often drive owners to overfeed. Pick consistent times, feed in a calm spot away from the litter box and from other pets that might cause competition, and use the same measured portion every time so you always know exactly how much your cat is eating. In multi-cat homes, feed separately or in spaced-out stations so a confident cat can’t hog the food while a shy one goes hungry.
Fresh water deserves the same consistency: keep clean water available at all times, ideally in more than one location, since cats often drink more when water is offered away from the food bowl. A steady routine also makes it far easier to notice the early warning signs that something is wrong — a skipped meal, a sudden surge in appetite or thirst, or slow weight change all stand out clearly against a stable baseline, letting you raise concerns with your veterinarian before a small problem becomes a big one.
Frequently Asked Questions
How often should I feed my cat?
Kittens under six months need three to four small meals a day, growing kittens two to three, and most adults do well on two measured meals daily. Many cats also thrive with several tiny grazing meals. Seniors usually keep the twice-daily routine unless a health condition calls for change.
How do I switch my cat to a new food?
Transition gradually over seven to ten days, mixing a little new food into the old and increasing the new while decreasing the old every couple of days. A slow change reduces stomach upset and food refusal.
When should a kitten switch to adult food?
Most cats stay on kitten or growth formula until about twelve months, when growth is largely complete. Large breeds like Maine Coons may stay on it a little longer. Ask your veterinarian to confirm timing for your cat.
Do senior cats need special food?
Many benefit from a diet adjusted for kidney, weight or dental health, but needs vary widely. The Cornell Feline Health Center advises regular checkups so feeding can be tailored, rather than assuming every older cat needs the same senior formula.
