Many chronic feline health conditions require dietary management; understanding the nutritional needs of cats with kidney disease, diabetes, and hyperthyroidism improves their welfare outcomes.
Nutritional management of chronic feline disease represents a high-welfare intervention because it affects quality of life directly and continuously. A cat eating an appropriate renal diet experiences slower disease progression, less uraemia, and better quality of life than one on a standard diet. A diabetic cat achieving remission through dietary change no longer requires twice-daily insulin injections — a welfare improvement for both cat and owner. The challenge is palatability: prescription diets that cats refuse do not provide welfare benefit. Trialling different formulations and brands, warming food to enhance palatability, and working with veterinary nutritionists to find acceptable options maximises the welfare benefit of these interventions.
