Understanding Cat Nutrition
Cats are obligate carnivores, meaning they must eat meat to survive. This fundamental difference from dogs and humans shapes their nutritional requirements.
Essential Nutrients for Cats
Protein: Cats need significantly more protein than dogs or humans. Animal-based protein provides essential amino acids like taurine that cats cannot produce themselves.
Taurine: This amino acid is critical for heart health, vision, and reproduction. Deficiency can lead to serious health problems.
Arachidonic Acid: An essential fatty acid cats must get from their food.
Vitamin A: Cats cannot convert beta-carotene to vitamin A like dogs can—they need pre-formed vitamin A from animal sources.
Moisture: Cats have a low thirst drive and need moisture in their food. Wet food helps prevent urinary tract issues.

Our Recommendation
Many veterinarians recommend feeding both wet and dry food. This provides the moisture cats need while maintaining dental benefits from dry food.
Frequently Asked Questions
How much should I feed my cat?
Portion depends on weight, age, activity level, and food type. Generally, adult cats need 20-30 calories per pound of body weight daily. Always follow package guidelines and adjust based on your cat's condition.
Should I feed my cat wet or dry food?
Both have benefits. Many experts recommend feeding both—a 50/50 split provides moisture from wet food and dental benefits from dry food.
Why is my cat a picky eater?
Cats can be picky for various reasons: stress, illness, food temperature, or simply preference. Try warming food slightly, offering different textures, or mixing wet and dry food.
How do I switch cat foods?
Gradually over 7-10 days. Start with 75% old food, 25% new food, and gradually increase the new food.
What ingredients should I avoid in cat food?
Generic "meat by-products," excessive plant proteins, artificial colors/preservatives, and high amounts of carbohydrates.
