What Do Cats Eat & Why It Matters for Health
Understanding what do cats eat is the foundation of feline health. Cats are obligate carnivores, meaning they need animal-based protein to survive.
🥩 Healthy Diet Basics:
- High-quality protein (chicken, fish, turkey)
- Taurine (essential amino acid)
- Moderate fat
- Low carbohydrates
- Fresh, clean water daily
👉 In my experience, many health problems start with poor diet choices—especially cheap, low-quality cat food.
