Wondering what can cats eat besides their regular cat food? The safest answer starts with a complete and balanced feline diet, then allows carefully prepared human foods as occasional treats. Cats have different nutritional needs than people, so a bite that is harmless for you may be unsafe, unnecessary, or too rich for your cat.

This guide is for general education. If your cat has a medical condition, takes medication, is on a prescription diet, or may have eaten a toxic food, contact your veterinarian for advice.
What Can Cats Eat Safely?
Most cats should get nearly all of their daily nutrition from a complete and balanced cat food. Small amounts of plain, fully cooked meat or other appropriate foods may work as occasional treats, but treats should never replace meals or become the main diet.
Cats are obligate carnivores. Their bodies depend on nutrients found in animal products, including specific amino acids, fatty acids, vitamins, and minerals. A quality cat food is formulated to provide those nutrients in the right proportions. A plate of human food, even if it contains meat, usually does not provide a complete feline diet.
For a practical reference on feline nutrition, see the Cornell Feline Health Center's feeding guidance. The right everyday food depends on your cat's age, health, body condition, activity level, and veterinary recommendations.
Safe occasional foods for many healthy cats
When prepared simply and served in tiny portions, these foods are commonly used as occasional treats for healthy cats:
- Plain cooked chicken or turkey: Remove bones, skin, heavy fat, sauces, onion, garlic, and seasoning.
- Plain cooked lean beef: Serve a small amount without salt, butter, gravy, or spice blends.
- Fully cooked fish: Choose boneless fish with no oil, brine, breading, or seasoning. Fish should be an occasional treat, not a daily diet.
- Cooked egg: Offer a small piece of plain, fully cooked egg. Do not serve raw egg.
- Plain pumpkin: A small amount may be appropriate for some cats, but ask your veterinarian before using it to manage diarrhea, constipation, or another symptom.
Introduce only one new food at a time. That makes it easier to notice vomiting, diarrhea, itching, ear irritation, or a refusal to eat. Stop the new food if a reaction appears, and contact your veterinarian if symptoms are severe or persistent.
Which Human Foods Should Cats Avoid?
Never intentionally feed cats chocolate, caffeine, alcohol, raw yeast dough, onions, garlic, chives, or heavily seasoned foods. Keep grapes, raisins, products containing xylitol, bones, and raw animal foods away from cats too, and call a veterinarian promptly after a suspected exposure.
Some foods are dangerous because they contain toxic compounds. Others are risky because they can cause choking, obstruction, digestive upset, bacterial exposure, or an unbalanced diet. The ASPCA's people-food safety list is a useful reference, but it does not replace a veterinarian's advice for your individual cat.
| Food or ingredient | Why to avoid it |
|---|---|
| Onions, garlic, chives, and related seasonings | Can irritate the digestive system and damage red blood cells. Cats are especially susceptible. |
| Chocolate, coffee, tea, energy drinks, and caffeine | May cause vomiting, abnormal heart rhythm, tremors, seizures, or worse. |
| Alcohol and raw yeast dough | Can cause alcohol toxicity, dangerous gas buildup, bloating, or other emergencies. |
| Grapes and raisins | There is no safe reason to offer them. Keep them away and call your veterinarian after ingestion. |
| Bones, especially cooked bones | Can splinter, injure the mouth or digestive tract, or cause an obstruction. |
| Raw meat, raw eggs, and raw diets | May expose cats and people to harmful bacteria or parasites and may not be nutritionally complete. |
| Salty, fatty, or highly seasoned leftovers | Can upset digestion and add unnecessary sodium or calories. Seasonings may hide toxic ingredients. |
Do not induce vomiting unless a veterinarian or poison-control professional specifically tells you to do so. Save the food package or ingredient list, estimate how much your cat may have eaten, and note when the exposure happened. That information can help the veterinary team make a faster decision.
How Much Human Food Can a Cat Eat?
Human food should be a small treat, not a second meal. A common veterinary guideline is to keep treats and snacks at about 10 percent or less of daily calories, with the remaining calories coming from complete and balanced cat food. Your veterinarian can set a safer limit for your cat.
Portion size is one of the most important answers to what can cats eat. Even a safe food can cause problems when it displaces balanced nutrition or adds more calories than a small cat needs. A bite-sized piece may be enough to provide variety without changing the nutritional balance of the day.
Veterinary nutrition guidance commonly recommends that about 90 percent of a cat's daily calories come from complete and balanced food, while treats make up no more than about 10 percent. The exact amount varies with body weight, age, activity, neuter status, medical conditions, and the calorie density of the treat. The VCA guide to cat treats explains why a treat budget matters, especially for cats that need weight management or a prescription diet.
- Use a very small portion the first time.
- Do not add table scraps on top of a full treat allowance.
- Count treats used for medication, training, or enrichment.
- Avoid high-fat sauces, gravy, butter, salt, and seasoning.
- Keep treats occasional so your cat continues eating its balanced food.
If your cat is overweight, underweight, diabetic, allergic, prone to urinary problems, or eating a veterinary therapeutic diet, ask your veterinary care team before offering human food. Some diets only work as intended when extra foods and treats are tightly controlled.
Why Complete and Balanced Cat Food Matters
A complete and balanced cat food should supply the foundation of your cat's diet. Treats such as cooked meat can add variety, but they do not reliably provide every nutrient a cat needs. Read the nutritional adequacy statement and choose a formula suited to your cat's life stage and health.
Human foods are not automatically healthier than cat food. Cats need a precise nutrient profile, including nutrients that are easy to miss in homemade meals. Feeding mostly meat, for example, can create an imbalance because muscle meat alone does not provide every vitamin and mineral a cat needs.
When comparing everyday food, look for a product labeled complete and balanced for the appropriate life stage. Kittens, adult cats, and senior cats may need different formulations. If you are considering homemade or raw feeding, discuss it with a veterinarian or a board-certified veterinary nutritionist first. Homemade recipes can be difficult to balance, and raw diets can introduce infectious risks without a clear proven benefit for every cat.
For a broader look at products and questions to discuss with your veterinarian, you can review the Hooves and Paws cat supplements guide. Supplements should not be added automatically to a balanced diet. Some can interact with medications or create excesses, so veterinary approval matters.
What Should Cats Drink?
Fresh, clean water should be available every day. Wet cat food can contribute meaningful moisture, while water fountains, multiple bowls, and clean bowl placement may encourage some cats to drink. Contact your veterinarian if a change in drinking or urination is sudden or pronounced.
Water is a core part of feeding basics, even though many cats drink less visibly than dog owners expect. Put clean water in a quiet, easy-to-reach location and refresh it regularly. Some cats prefer a wide, shallow bowl, while others drink more readily from a fountain.
Wet food contains more water than dry food and may help increase total fluid intake, but the best feeding format depends on your cat's health and preferences. A sudden increase in thirst, unusually frequent urination, repeated vomiting, or signs of dehydration deserves veterinary attention rather than a home diet experiment.
Feeding Basics for Kittens, Adults, and Senior Cats
Life stage changes the answer to what can cats eat every day. A growing kitten has different nutrient and calorie needs than an adult cat. Older cats may need a veterinary assessment for dental disease, kidney concerns, weight changes, or other conditions that affect appetite and diet.
- Kittens: Feed a complete and balanced growth formula as directed by your veterinarian. Human-food treats should be rare and should not crowd out growth nutrition.
- Healthy adults: Use measured portions of an appropriate complete and balanced formula. Keep extras small and account for them in the daily routine.
- Senior cats: Monitor appetite, hydration, body condition, chewing comfort, and changes in behavior. Ask your veterinarian whether the current food still fits your cat's needs.
- Cats with health conditions: Follow the prescribed diet and ask before adding toppers, treats, supplements, or human food.
A cat that suddenly refuses food should not simply be tempted with a buffet of new treats. Cats can become seriously ill when they stop eating, particularly if they are overweight or already have a medical problem. If appetite changes, call your veterinarian.

When Should You Call a Veterinarian?
Call your veterinarian promptly after a possible toxic-food exposure or when your cat shows repeated vomiting, severe diarrhea, tremors, weakness, seizures, trouble breathing, collapse, pale gums, or a sudden refusal to eat. Do not wait for symptoms to become severe after a known toxin exposure.
Food questions become urgent when your cat may have eaten a toxic ingredient or when symptoms are more than mild and brief. Contact your veterinarian, an emergency veterinary hospital, or a trusted animal poison-control service as soon as possible after exposure to chocolate, caffeine, alcohol, onions, garlic, medications, or an unknown substance.
Seek emergency care for breathing difficulty, collapse, seizures, severe weakness, repeated vomiting, a swollen or painful abdomen, uncontrolled bleeding, or signs of a serious allergic reaction. For less dramatic symptoms, call your veterinary team for guidance instead of trying to correct the problem with more food, milk, oils, or supplements.
Frequently Asked Questions
Can cats eat cooked chicken?
Many healthy cats can have a small amount of plain, fully cooked chicken as an occasional treat. Remove bones, skin, excess fat, salt, onion, garlic, sauces, and seasonings. Chicken should not replace a complete and balanced cat food.
Can cats eat tuna?
A small amount of plain, fully cooked tuna may be an occasional treat, but tuna prepared for people should not become a cat's regular diet. Avoid tuna in oil, brine, sauces, or seasoning, and ask your veterinarian if your cat has a medical condition.
Can cats drink milk?
Many adult cats do not digest lactose well, so milk can cause stomach upset or diarrhea. Fresh water is the better everyday drink. Do not use milk to treat a suspected toxin exposure or to encourage a cat that is ill to eat without veterinary guidance.
Can cats eat eggs?
Plain, fully cooked egg can be an occasional treat for many healthy cats. Serve only a small amount and avoid raw egg, butter, salt, cheese, and seasoning. Ask your veterinarian before adding it to a cat with allergies or a therapeutic diet.
What can I feed a cat if I do not have cat food?
For a short-term situation, contact a veterinarian or local animal shelter for guidance. A small amount of plain, fully cooked, unseasoned meat may be acceptable for many healthy cats, but it is not a complete long-term diet. Never use onion-seasoned leftovers, bones, raw dough, chocolate, or caffeinated foods.
Knowing what can cats eat is less about finding a long list of human foods and more about protecting the balance of the everyday diet. Keep complete and balanced cat food at the center, offer only simple treats in small portions, provide fresh water, and call your veterinarian whenever your cat's health or safety is uncertain.
