Cat Nutrition and Welfare: What Cats Actually Need to Eat

Cats are obligate carnivores whose nutritional needs are frequently misunderstood, leading to preventable health problems and welfare harm.

Key Facts

Cats cannot synthesize taurine and require it from animal-based protein
Plant-based cat diets risk serious nutritional deficiencies including taurine and arachidonic acid
Lower urinary tract disease is strongly linked to dry food diets in cats
Cats evolved to obtain moisture from prey and rarely drink sufficient water from bowls
High-quality wet food or raw diets better match feline nutritional physiology than dry kibble

Welfare Considerations

Cats fed inappropriate diets develop preventable diseases. Taurine deficiency causes dilated cardiomyopathy and blindness. Chronic dehydration from dry food diets contributes to kidney disease and urinary tract problems. Obesity from high-carbohydrate dry food causes diabetes and joint disease. The pet food industry markets products that are convenient for owners rather than optimal for cats, and nutritional literacy among cat owners is low.

What You Can Do

Feed cats a diet primarily of high-quality wet food to ensure adequate hydration
Avoid plant-based cat diets unless under close veterinary supervision with supplementation
Research the specific amino acid requirements cats have that must come from animal protein
Consult a veterinary nutritionist if you have concerns about your cat's diet
Advocate for better nutritional labeling on pet foods to help owners make informed choices
