Cats aged 11 and above have specific nutritional needs that differ from younger adults. Appropriate senior diets support kidney health, muscle mass, joint comfort, and cognitive function in ageing cats.
Senior cat nutrition is one of the most impactful areas of companion animal welfare because poor dietary choices accelerate age-related disease. The greatest tension is around protein: kidneys need phosphorus restriction, but muscles need adequate high-quality protein. Modern senior kidney diets balance this with controlled phosphorus and highly digestible protein sources. Wet food is often preferable for hydration and ease of eating. Cats with dental disease must be assessed before assuming they can eat dry kibble. Weight monitoring is critical — both obesity and muscle wasting are common in senior cats and require different dietary responses. Supplements such as omega-3 fatty acids (EPA/DHA) and antioxidants (vitamin E, selenium) are supported by evidence for cognitive and inflammatory conditions. Regular veterinary nutritional assessment should be standard from age 11 onwards.
