Cat Nutrition Guides
Cats are obligate carnivores, so most human foods are extras at best and problems at worst. These guides explain what is safe, what to avoid, and how much is too much, one food at a time. To check how much your cat should actually be eating, start with our cat nutrition calculator.
These guides are general information, not veterinary advice. Every cat is different, and a food that is fine for most cats may not suit yours. Check with your veterinarian before adding a new food, especially if your cat is a kitten, is pregnant, or has a health condition. If your cat has eaten something toxic, contact your vet or a pet poison helpline immediately.
How much should your cat eat?
Treats and human foods should be a small slice of the day, not the main event. Use the Cat Nutrition Calculator to find your cats daily calorie target, so you know how little room there is for extras.

How to Think About Cat Treats and Human Food
A few principles that make the individual food questions easier
Meat first, always
Cats are obligate carnivores and need nutrients found in animal tissue, such as taurine and vitamin A. A complete, balanced cat food should be the foundation of the diet. Everything else is a garnish, not a food group.
The 10 percent rule
Keep all treats and extras to about 10 percent of daily calories. For a small animal like a cat that is very little, often just a teaspoon or two, which is why moderation is the whole game with human foods.
Not toxic is not the same as good
Many foods, like cheese or strawberries, are not poisonous but still offer cats nothing they need and can upset their stomach. Safe in a nibble does not mean it belongs in the bowl.
Know the true toxins
A short list of foods is genuinely dangerous: onions and garlic, grapes and raisins, chocolate, alcohol, and xylitol. These are not moderation foods, they are never foods, and they can warrant an urgent vet call.
Frequently Asked Questions About Cat Nutrition
Common questions about feeding cats human foods
Are cats obligate carnivores?
Yes. Cats are obligate carnivores, which means they are built to get most of their nutrition from animal protein and fat. They need certain nutrients, such as taurine, arginine, vitamin A, and arachidonic acid, in a form found in meat. This is why a complete, balanced cat food should make up almost all of their diet, and why human foods and fruits are only ever occasional extras.
How much human food can I give my cat?
A useful rule is that treats and extras of any kind should make up no more than about 10 percent of your cats daily calories, with the other 90 percent coming from a complete, balanced cat food. For most cats that 10 percent is only a teaspoon or two of an extra, so a nibble of a safe food now and then is fine, but regular portions are not.
What foods are toxic to cats?
Foods that are genuinely toxic to cats include onions, garlic, chives, and leeks, grapes and raisins, chocolate, caffeine, alcohol, raw dough, and anything containing the sweetener xylitol. These are different from foods that are simply unnecessary or hard to digest, such as cheese or fruit. If your cat eats a known toxic food, contact your vet or a pet poison helpline right away.
Do cats taste sweetness?
No. Cats lack the taste receptors for sweetness, so they do not enjoy fruit the way people or even dogs do. A cat that shows interest in melon or berries is usually drawn to the moisture or texture rather than the sugar. This is another reminder that sweet human foods offer cats little and are best kept to tiny, occasional tastes.
Can these guides tell me if my cat is safe?
These guides are general information to help you understand which everyday foods are safe, risky, or best avoided. They are not veterinary advice and cannot account for your cats age, weight, and health. Always check with your vet before adding a new food, especially if your cat has a medical condition, and call your vet if your cat reacts badly to something they have eaten.
