Cats are masters at hiding change. Your once-energetic kitten is suddenly sleeping 18 hours a day, moving a little slower, and maybe being pickier about food. If your cat is 7 years or older, their nutritional needs have shifted β and their feeding schedule should shift too.
Here's a practical guide to feeding senior cats, covering how much, how often, and what to watch for as they age.
When is a cat considered "senior"?
Most vets consider cats senior at 7 years old. By 11β12, they're "super senior" or geriatric. These aren't just labels β real physiological changes happen:
- Metabolism slows in the 7β10 range, increasing obesity risk
- Metabolism can speed up again after 11β12 as cats lose the ability to digest fat and protein as efficiently
- Kidney function gradually declines β the most common health issue in older cats
- Muscle mass decreases (sarcopenia), requiring more protein to maintain
- Dental health may affect their ability to eat kibble
How much to feed a senior cat
Caloric needs depend on your cat's weight, body condition, and activity level. Here are general guidelines:
| Cat Weight | Indoor/Low Activity | Moderate Activity | Underweight/High Metabolism |
|---|---|---|---|
| 6 lbs | 150 β 170 cal/day | 170 β 200 cal/day | 200 β 230 cal/day |
| 8 lbs | 180 β 200 cal/day | 200 β 240 cal/day | 240 β 280 cal/day |
| 10 lbs | 200 β 230 cal/day | 230 β 270 cal/day | 270 β 320 cal/day |
| 12 lbs | 220 β 260 cal/day | 260 β 300 cal/day | 300 β 360 cal/day |
| 14 lbs | 240 β 280 cal/day | 280 β 330 cal/day | 330 β 400 cal/day |
These are starting points. Your cat's actual needs will vary. Use our pet food calculator for a more personalized estimate based on your specific cat's details.
How often to feed a senior cat
This is where it gets interesting. The right frequency depends on your cat's age bracket and health:
Ages 7β10: Two meals a day (with possible reduction)
Cats in this range are at the highest risk of weight gain. Their metabolism has slowed but their appetite usually hasn't. Stick with two measured meals per day β typically morning and evening. Avoid free-feeding (leaving food out all day), which makes it impossible to track how much they're actually eating.
Ages 11+: Three to four smaller meals a day
Older cats often do better with smaller, more frequent meals. Their digestive systems process smaller portions more efficiently, and eating more often helps maintain energy levels throughout the day. If three meals isn't practical for your schedule, two meals plus a small snack works too.
Cats with health conditions
If your senior cat has been diagnosed with kidney disease, diabetes, hyperthyroidism, or other conditions, your vet's feeding recommendations take priority. Some conditions require very specific meal timing β diabetic cats on insulin, for example, need meals coordinated with injections.
What to feed a senior cat
Protein: more, not less
There's an outdated idea that senior cats need less protein. The opposite is true. Older cats need more high-quality protein to maintain muscle mass. Look for foods where a named animal protein (chicken, turkey, fish) is the first ingredient, with at least 40% protein on a dry matter basis.
Wet food vs. dry food
Wet food has real advantages for senior cats:
- Hydration: Wet food is 75β80% water. Senior cats often don't drink enough, and chronic mild dehydration stresses the kidneys. More moisture in food = less work for kidneys.
- Easier to eat: Cats with dental issues or missing teeth handle wet food much better than hard kibble.
- Higher palatability: Picky older cats are more likely to eat wet food.
If your cat has always eaten dry food, you don't need to switch entirely. A mix works well β dry for one meal, wet for the other. Just make sure you're accounting for the calorie difference (wet food has fewer calories per volume than kibble).
Key nutrients for senior cats
- Phosphorus: Should be moderate to low, especially after age 10. High phosphorus accelerates kidney disease progression.
- Omega-3 fatty acids: Help with joint health, coat quality, and inflammation. Fish-based foods provide this naturally.
- Fiber: A small amount of fiber helps with digestive regularity, which is a common issue in older cats.
- B vitamins: Senior cats can become deficient in B12 and other B vitamins. Many senior-specific formulas supplement these.
Warning signs to watch for
Changes in eating behavior are often the first sign of health problems in senior cats. Pay attention to:
- Eating less: Could indicate dental pain, nausea, kidney disease, or other illness
- Eating more but losing weight: Classic sign of hyperthyroidism, very common in cats over 10
- Drinking more water: Can signal kidney disease or diabetes
- Vomiting after meals: Occasional hairballs are normal; frequent vomiting isn't
- Ignoring food then eating ravenously: May indicate nausea or gastrointestinal issues
Any sudden change in eating habits warrants a vet visit. With senior cats, catching things early makes a huge difference in outcomes.
Practical tips for feeding senior cats
- Warm the food slightly. Senior cats with diminished sense of smell are more interested in food served at room temperature or slightly warmed. 10 seconds in the microwave makes a difference.
- Elevate the food bowl. Raised bowls (2β4 inches off the ground) are easier on arthritic necks and joints.
- Weigh your cat monthly. Weight loss in senior cats is gradual and easy to miss when you see them every day. A kitchen scale works for small cats; otherwise, weigh yourself, then weigh yourself holding the cat.
- Don't abruptly change foods. Senior cats have more sensitive stomachs. Any food switch should happen gradually over 7β10 days. See our guide on transitioning to new food β the same principles apply to cats.
- Keep fresh water available always. Consider a cat water fountain β many cats prefer running water, and the movement encourages more drinking. Check our guide on hydration needs for general principles.
Sample feeding schedule for a 10 lb senior cat
Here's what a day might look like for an average 10 lb indoor senior cat needing about 220 calories:
- 7:00 AM: ΒΌ cup dry senior kibble (~90 calories)
- 5:30 PM: One 3 oz can of wet food (~100 calories)
- 9:00 PM: Small treat or 1 tablespoon wet food (~30 calories)
Adjust portions based on your cat's weight trend. If they're gaining, trim back slightly. If they're losing, add a bit more β especially protein-rich wet food.
The bottom line
Feeding a senior cat well isn't complicated, but it does require more attention than when they were younger. Focus on high-quality protein, adequate hydration (wet food helps), measured portions, and regular weigh-ins. Small adjustments now can add healthy years to your cat's life.
