Feeding a Senior Cat: What to Know

Aging changes needs

As cats enter their senior years, their metabolism, digestion, and ability to absorb nutrients can change. Some slow down and gain weight, while many older cats lose weight and muscle. Because needs vary so much from cat to cat, feeding a senior well means watching the individual rather than following one rule.

Weight can go either way

Keep a close eye on body condition and weigh your cat regularly. Weight gain stresses joints and raises health risks, while unexplained weight loss can be an early sign of common senior conditions like kidney disease, hyperthyroidism, or diabetes. Any noticeable change is a reason to call the vet, not to simply adjust the bowl.

Palatability and hydration

Older cats may eat less due to a duller sense of smell, dental discomfort, or nausea. Warming food slightly, offering aromatic wet food, and providing plenty of fresh water or a fountain all encourage intake and hydration, which is especially important for aging kidneys.

Digestive support

Senior digestion can become more sensitive. A gentle, highly digestible diet helps, and a vet-recommended probiotic such as [Purina FortiFlora](/products/purina-fortiflora-probiotic-supplement) may support healthy gut bacteria and appetite in older cats. Introduce any change slowly to avoid upsetting a sensitive stomach.

Partner with your vet

Senior cats benefit from more frequent checkups, often twice a year, with bloodwork to catch age-related conditions early. Let those results guide diet decisions — a therapeutic food may be recommended for specific issues. Nutrition works best as part of a vet-guided senior care plan.
