Key Cat Nutrition Principles in the UK 2026
Cats thrive on diets mimicking natural prey: high animal protein (30-50%+), moderate fat, low carbohydrates (70% in wet/fresh). UK regulations require AAFCO or FEDIAF compliance for "complete and balanced" labels, but top brands exceed basics with human-grade meats, no artificial additives, and third-party testing.
High-moisture wet cat food and fresh cat food support urinary health by promoting hydration, reducing FLUTD risk. Grain-free cat food avoids fillers like wheat or corn, suiting sensitive stomachs or allergies. Organic cat food and ethical sourcing appeal to eco-aware owners. Portion control is vital—typically 20-35 kcal per pound of body weight daily—to avoid obesity, common in indoor UK cats.
Always transition foods over 7-10 days and consult your vet, especially for health conditions. Monitor coat shine, energy, weight, and stool quality for the best cat food match.
