Cat Senior Nutrition and Healthy Ageing

Senior cats have distinct nutritional needs that change through the ageing process and require adjustment to support healthy physical and cognitive function.

Key Facts

Cats are considered senior from age 11, geriatric from 15 — life stage-appropriate nutrition changes significantly across this range
Protein requirements may increase in older cats due to reduced digestive efficiency, despite a common belief that protein should be restricted in seniors
Energy requirements often decline in middle age but may increase again in geriatric cats due to reduced nutrient absorption
Cognitive dysfunction, kidney disease, dental disease, and hyperthyroidism all affect nutritional needs in older cats
Palatability is critical for senior cats with reduced appetite — warming food and adding water can improve acceptance significantly

Welfare Considerations

Senior cat nutrition is complex and frequently managed suboptimally. Cats fed senior diets formulated for middle-aged weight management may be nutritionally inadequate for elderly cats with increased protein needs and reduced absorption. Individual health conditions impose additional nutritional constraints. Annual veterinary health screening from age 10 allows dietary adjustments to be guided by real clinical data rather than generalised age-based recommendations.

What You Can Do

Schedule biannual veterinary health checks for cats over 10 years to guide nutritional adjustments
Discuss your senior cat's specific nutritional needs with your vet rather than relying solely on commercial senior diet labelling
Monitor body weight and muscle condition monthly in elderly cats — muscle loss (sarcopenia) is distinct from and more serious than fat gain
Ensure food is always palatable and accessible — elderly cats with reduced appetite benefit from smaller, more frequent meals of warmed food
