Nutrition is foundational to cat welfare—as obligate carnivores with specific metabolic requirements, cats are uniquely vulnerable to both deficiency and excess. Understanding feline nutritional science enables welfare-optimised feeding decisions.
Cats are obligate carnivores with nutritional requirements reflecting evolutionary adaptation to prey-based diets: they cannot synthesise taurine (essential for cardiac and retinal health), arachidonic acid, or adequate niacin from precursors, requiring dietary supply. They have limited ability to process high carbohydrate loads due to low intestinal disaccharidase activity. Their gluconeogenic pathway is constitutively active—requiring protein for energy even when carbohydrates are available. Feeding cats as if they were omnivores creates welfare risks from nutrient deficiency or metabolic mismatch.
Wet food (canned, pouched) provides approximately 75-80% moisture—closely reflecting the water content of natural prey. Cats have evolved a low thirst drive, relying on food moisture for hydration. Dry food provides only 8-10% moisture, creating relative dehydration in cats fed exclusively dry food. Evidence links exclusive dry food feeding with higher rates of urinary tract disease, chronic kidney disease, and diabetes mellitus—all significant welfare conditions. Incorporating substantial wet food or raw food supports feline welfare through adequate hydration.
Cats naturally eat 10-16 small meals daily, reflecting their rodent prey hunting pattern. Single or twice-daily feeding of large portions is metabolically appropriate for some cats but may not satisfy the behavioural feeding drive, contributing to boredom and over-rapid consumption. Puzzle feeders and portion-divided feeding systems better replicate natural feeding patterns. For ad libitum fed cats prone to obesity, measured portions maintain body condition without hunger compromise.
Kittens require higher protein and energy density than adults; pregnant and lactating queens require substantial additional calories and calcium. Senior cats benefit from modified protein, phosphorus, and caloric density adjustments based on concurrent health conditions. Life-stage appropriate feeding maintains welfare across all ages by meeting changing nutritional needs rather than applying generic adult formulations throughout a cat's life.
