Cats are obligate carnivores, so they need nutrients from animal products. Their diet should include protein, fat, and carbohydrates in those proportions, plus vitamins, minerals, fatty acids, and amino acids.
Food
Cats should eat high-quality commercial cat food, which is formulated specifically for them. Homemade and raw food diets often don’t meet a cat’s nutritional needs.
Protein
Cats need more protein than dogs. Kittens need especially high amounts of protein to help them build muscle.
Water
Cats need access to clean, fresh water at all times. They lose water through their bodies, and they need it for urinary tract health.
Vitamins
Vitamins are important for regulating body processes. Some vitamins to look for include:
Vitamin A: Supports cell development, growth, vision, and immune function
Vitamin D: Supports calcium metabolism and skeletal health
Vitamin E: An antioxidant that supports the immune system and healthy skin and coat
Vitamin K: Supports blood clotting and bone formation
Supplements
Supplements are usually not necessary if you’re feeding a balanced diet, and they can be harmful if given without a veterinarian’s approval.
