What should I feed my senior cat?

Cats are considered senior from about age 11, and geriatric from age 15. The nutritional needs of older cats differ significantly from younger adults, and getting senior nutrition right can meaningfully extend both the length and quality of your cat's life.

The paradox of senior cat nutrition

Many commercial "senior" cat foods reduce protein — the opposite of what most senior cats need. Research shows that older cats actually absorb protein less efficiently and need more protein to maintain muscle mass (lean body mass), not less. Look for senior foods with protein content above 35% dry matter.

The exception: cats with diagnosed chronic kidney disease (CKD) — the most common senior cat disease — do need phosphorus restriction and may need reduced protein levels under veterinary supervision. This is a medical decision, not a general recommendation.

Moisture is critical

Senior cats are at highest risk for kidney disease, urinary crystals, and dehydration. Wet food should form the foundation of a senior cat's diet. If your senior cat has been eating dry food, transitioning gradually to wet is one of the highest-impact nutritional changes you can make.

Energy needs shift

Some senior cats lose weight due to decreased absorption, dental pain, or disease. Others gain weight due to reduced activity. Monitor weight monthly and adjust portions accordingly — do not just "feed more" without understanding why weight is changing.

Dental health in seniors

Dental disease is extremely common in cats over 10 and significantly reduces food intake. If your senior cat is eating less, eating on one side, or dropping food, a dental examination is essential. Wet food is much easier to eat with painful teeth.

Key nutrients for senior cats

- Omega-3 fatty acids (EPA/DHA) — reduce inflammation, support joint and kidney health
- Antioxidants (vitamin E, vitamin C, selenium) — combat oxidative stress associated with aging
- B vitamins — older cats may absorb B vitamins poorly; wet food generally provides more
