Quick Answer:
Cats are obligate carnivores, meaning they must eat meat to survive. Safe proteins include cooked chicken, turkey, salmon, shrimp, and eggs. Cats cannot synthesize taurine on their own and require it from animal-based protein sources. Avoid onions, garlic, chocolate, grapes, lilies, and xylitol -- all are toxic to cats. When in doubt, check our guide below or consult your veterinarian.
As a cat owner, you've likely wondered "Can my cat eat this?" Unlike dogs, cats are obligate carnivores -- their bodies are designed to thrive on animal-based protein. They cannot synthesize essential nutrients like taurine, arachidonic acid, and preformed vitamin A from plant sources, making meat an absolute dietary requirement.
This comprehensive guide covers over 40 common foods, organized by category, so you always know what's safe to share with your feline companion. Remember: treats and human food should make up no more than 10% of your cat's daily caloric intake. The remaining 90% should come from a complete, balanced cat food formulated for your pet's age and health needs.
Proteins Cats Can and Cannot Eat
As obligate carnivores, protein should be the foundation of your cat's diet. Cooked, plain meats and fish provide essential amino acids including taurine, which cats cannot produce on their own. Always cook meat and fish thoroughly, remove all bones, and never serve seasoned or processed proteins. Check our detailed guides for tuna, chicken, salmon, and shrimp.
Proteins
Regular grooming combined with proper nutrition keeps your cat healthy and happy
Dairy Cats Can and Cannot Eat
Despite the popular image of cats drinking milk, most adult cats are actually lactose intolerant. After weaning, cats produce less lactase enzyme, making dairy difficult to digest. Small amounts of low-lactose options like hard cheese or plain yogurt may be tolerated, but dairy should never be a regular part of your cat's diet. See our guides on cheese and milk for more details.
Dairy
Fruits Cats Can and Cannot Eat
Cats lack sweet taste receptors, so most aren't drawn to fruit. However, some fruits can be offered as occasional treats in small amounts. Always remove seeds, pits, and rinds. Keep in mind that cats derive minimal nutritional benefit from fruit since their bodies are designed to process animal protein, not plant sugars.
Fruits
Vegetables Cats Can and Cannot Eat
While cats don't need vegetables in their diet, some can serve as safe, low-calorie treats. Pumpkin is particularly useful for cats with digestive issues due to its high fiber content. Always cook vegetables before offering them, and serve plain without salt, butter, or seasonings. Avoid spinach for cats with urinary or kidney issues due to oxalate content.
Vegetables
Grains & Other Foods Cats Can and Cannot Eat
Cats have limited ability to digest carbohydrates compared to dogs and humans. While small amounts of cooked plain rice or oatmeal are not harmful, grains provide very little nutritional value for cats. If your cat has digestive upset, a small amount of plain rice can help settle their stomach, but protein should always remain the dietary priority.

A proper diet tailored to your pet's species-specific needs makes all the difference
Most Dangerous Foods for Cats
If your cat consumes any of these foods, contact your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435) immediately:
| Food | Why It's Dangerous | Symptoms |
|---|---|---|
| Onions & Garlic | Destroys red blood cells (even more toxic to cats than dogs) | Weakness, lethargy, pale gums, collapse |
| Chocolate | Contains theobromine and caffeine | Vomiting, diarrhea, rapid breathing, seizures |
| Grapes & Raisins | Causes acute kidney failure | Vomiting, lethargy, decreased urination |
| Lilies | All parts are extremely toxic to cats (unique to cats!) | Vomiting, loss of appetite, kidney failure, death |
| Xylitol | Causes insulin release and liver failure | Vomiting, loss of coordination, seizures |
| Raw Fish | Destroys thiamine (vitamin B1), parasites risk | Loss of appetite, seizures, neurological damage |
Emergency: If Your Cat Eats Something Toxic
Call your veterinarian, the ASPCA Animal Poison Control Center at (888) 426-4435, or the Pet Poison Helpline at (855) 764-7661 immediately. Do not induce vomiting unless instructed by a professional. Note what your cat ate, the estimated amount, and the time of ingestion. Time is critical -- seek help immediately.
Toxic & Unsafe Foods
Cat Nutrition Basics
Cats have unique nutritional requirements that set them apart from dogs and other pets. As obligate carnivores, their bodies are specifically designed to derive nutrition from animal-based proteins. Here are the essential nutrients your cat needs:
| Nutrient | Why Cats Need It | Best Sources |
|---|---|---|
| Taurine | Essential for heart, vision, and reproduction -- cats cannot synthesize it | Chicken, turkey, fish, shellfish |
| Arachidonic Acid | Essential fatty acid for skin, coat, and inflammatory response | Animal fats, organ meats, fish |
| Preformed Vitamin A | Cats cannot convert beta-carotene to vitamin A like dogs can | Liver, fish oil, egg yolks |
A taurine deficiency in cats can lead to dilated cardiomyopathy (heart disease), retinal degeneration (blindness), and reproductive problems. This is why feeding dog food to cats is dangerous long-term -- dog food is not formulated to include adequate taurine levels for feline needs.
General Feeding Guidelines
Following these guidelines will help you safely share food with your cat:
✓ Do
- * Follow the 10% treat rule strictly
- * Prioritize animal-based proteins
- * Cook all meat and fish thoroughly
- * Remove all bones, skin, and fat
- * Introduce new foods one at a time
- * Ensure fresh water is always available
- * Choose cat-specific food (not dog food)
- * Consult your vet about your cat's specific needs
✗ Don't
- * Feed raw fish or raw meat regularly
- * Give milk or cream (lactose intolerance)
- * Share onions, garlic, or chives in any form
- * Keep lilies in homes with cats
- * Feed dog food as a substitute for cat food
- * Offer seasoned, spiced, or fried foods
- * Replace balanced cat food with human food
- * Ignore vomiting or digestive changes
Frequently Asked Questions
What human foods can cats safely eat?▼
Cats are obligate carnivores, so protein-based foods are the safest choice. Cats can eat cooked chicken, turkey, salmon, shrimp, eggs, and small amounts of lean beef. Some cats also tolerate small portions of cooked carrots, peas, pumpkin, blueberries, and watermelon. Always serve foods plain, cooked, and in small amounts. Remember that animal protein should always be prioritized over plant-based foods.
What foods are toxic to cats?▼
Toxic foods for cats include onions and garlic (even small amounts damage red blood cells), chocolate, grapes and raisins, xylitol (artificial sweetener), and lilies -- which are uniquely toxic to cats and can cause fatal kidney failure from even minor exposure. Raw fish can destroy thiamine (vitamin B1), leading to neurological problems. If your cat eats any toxic food, contact your vet or the ASPCA Poison Control Center at (888) 426-4435 immediately.
Can cats eat dog food?▼
Cats should not eat dog food regularly. Dog food lacks taurine, arachidonic acid, and sufficient protein levels that cats require as obligate carnivores. While a bite of dog food won't harm your cat, feeding it regularly can lead to serious nutritional deficiencies including heart disease (dilated cardiomyopathy), vision problems (retinal degeneration), and reproductive issues. Always choose food specifically formulated for cats.
Why can't cats be vegetarian?▼
Cats are obligate carnivores, meaning they must eat meat to survive. Unlike dogs and humans, cats cannot synthesize taurine, arachidonic acid, or preformed vitamin A from plant sources. These nutrients are only found naturally in animal tissues. A vegetarian or vegan diet will cause severe nutritional deficiencies in cats, leading to heart disease, blindness, and potentially death. There is no safe way to feed a cat a meat-free diet.
How much human food can I give my cat?▼
Treats and human food should make up no more than 10% of your cat's daily caloric intake. For an average 10-pound indoor cat eating about 200 calories per day, that means no more than 20 calories from treats -- roughly equivalent to one small piece of cooked chicken. Always introduce new foods one at a time, start with tiny portions, and watch for allergic reactions or digestive upset.
What should I do if my cat eats something toxic?▼
If your cat eats something toxic, contact your veterinarian, the ASPCA Animal Poison Control Center at (888) 426-4435, or the Pet Poison Helpline at (855) 764-7661 immediately. Do not induce vomiting unless directed by a professional. Note what your cat ate, how much, and when. Time is critical with cat poisoning -- especially with lilies, where even small exposures require immediate emergency treatment.
