Companion animal nutrition is an area of genuine scientific complexity with significant welfare implications. Understanding evidence-based feeding principles helps owners provide optimal nutrition for their pets.
Companion animal nutrition directly affects health, longevity, and quality of life. Nutritional deficiencies cause preventable disease — calcium deficiency causes pathological fractures, taurine deficiency causes cardiac disease, obesity causes musculoskeletal pain. Nutritional excesses and imbalances from unvalidated diets can be equally harmful. Owner enthusiasm for "natural" feeding approaches sometimes overrides evidence of nutritional risk. The welfare implications of poor nutrition accumulate over time, often not becoming visible until disease is established. Evidence-based nutrition from veterinary nutritionist guidance provides the best welfare foundation.
