The nutritional needs of senior cats change significantly with age, and appropriate dietary management is one of the most impactful ways to maintain health and welfare in older cats.
Senior cat nutrition is not a single formula but a changing set of requirements that must be matched to each cat individual health status. A cat with chronic kidney disease needs phosphorus restriction; a cat with hyperthyroidism needs iodine management; a cat with dental disease needs soft food it can eat comfortably. The welfare-optimal approach combines regular veterinary monitoring of health status with dietary adjustment as conditions evolve. Assuming a senior cat food brand is appropriate without veterinary assessment of the specific cat conditions is a common welfare gap — the diet must match the individual, not just the age bracket.
