What a cat actually needs from food
Cats are obligate carnivores: Cornell's Feline Health Center puts it plainly — their nutrition has to come from animal tissue, in proportions close to what a hunter would eat, which means a lot of protein, a moderate amount of fat and very little carbohydrate. That one fact explains most feeding advice worth keeping.
- Water first. The ASPCA calls water the most important nutrient of all — and a cat living on dry food takes in very little of it from the bowl.
- Taurine is not optional. Cats cannot make enough taurine themselves; it has to come from animal-origin food, and it protects the heart and eyes.
- Extra supplements are usually a risk, not a bonus. If the diet is complete and balanced, Cornell advises against adding vitamins or minerals without a vet's approval.
| Food type | Water content | What it means at home |
|---|---|---|
| Dry kibble | About 6-10% | Cheapest and easiest to leave out — but the least water per bite. Store it airtight, watch the expiry date (vitamins fade and fats turn rancid over months), and measure portions rather than topping up the bowl. |
| Semi-moist | About 35% | A middle ground on cost and palatability. Dries out quickly once the pack is open, so it suits a smaller household. |
| Canned / wet | At least 75% | The closest thing to a food that is also a drink, and usually the most palatable. Refrigerate whatever is left in an opened can. |
Reading a label in three steps
- Find the AAFCO statement. A food carrying an AAFCO nutritional guarantee is considered complete and balanced, and the statement names the life stage it is complete for — kitten, adult, or all life stages.
- Read the first few ingredients. They are listed in order of decreasing weight, so animal protein near the top is a good sign.
- Count the treats. Cornell's ceiling is 10-15% of daily calories, and the ASPCA is stricter with kittens at 5% of daily nutrient intake. Treats are where otherwise balanced diets quietly fall apart.
Two exceptions worth knowing: raw meat is not a safe treat (Cornell flags the infection risk), and cow's milk is a poor one, since many cats are lactose intolerant. And if your cat stops eating altogether, that is a veterinary question rather than a food question — a cat that refuses food and loses weight can deteriorate quickly.
