As cat parents, we love to spoil our furry companions with little tastes of our meals — a nibble of meat here, a lick of milk there. But not all human foods are safe for cats. In fact, some common kitchen items can be toxic or even life-threatening. Knowing the foods cats should not eat is essential to protect your feline’s health and avoid emergency vet visits. If you’re wondering what your cat should never eat, this informational guide will walk you through the most dangerous foods to avoid and what to do if your cat accidentally ingests something harmful.
Why It’s Important to Know Toxic Foods
Cats have very different metabolisms from humans. What seems like a minor snack to us could lead to vomiting, kidney failure, or worse for your pet. Knowing what foods cats should not eat helps you protect their health and avoid emergency vet visits.
Many owners learn the hard way—by feeding their cat something seemingly innocent, like onion soup or a piece of chocolate, and rushing them to the vet afterward. Prevention is far easier than treatment.
Top Human Foods Cats Should Not Eat
1. Onions, Garlic, and Chives
These common ingredients can destroy red blood cells in cats and cause anemia. Even small amounts—cooked, raw, or powdered—can be harmful.
2. Chocolate
Chocolate contains theobromine, which is toxic to cats. Dark chocolate is particularly dangerous, but all types should be avoided.
3. Grapes and Raisins
Even a small amount can lead to kidney failure in cats. Scientists still aren’t sure why, but the results are consistently dangerous.
4. Alcohol
Cats’ bodies can’t metabolize alcohol. Just a tablespoon can lead to liver failure or even death.
5. Caffeine (Coffee, Tea, Energy Drinks)
Caffeine stimulates the nervous system and heart. Symptoms of poisoning include hyperactivity, tremors, and seizures.
6. Bones and Fat Trimmings
Cooked bones can splinter and cause internal damage. Fat can lead to pancreatitis.
7. Raw Dough
Yeast continues to rise in a cat’s stomach, potentially causing bloating and alcohol poisoning.
8. Xylitol (Artificial Sweetener)
Found in sugar-free gum, candy, and some peanut butters, xylitol can cause insulin release, leading to hypoglycemia and liver failure.
9. Milk and Dairy Products
Despite the stereotype, most adult cats are lactose intolerant. Milk can cause digestive upset, gas, and diarrhea.
10. Tuna (in excess)
While cats love tuna, too much can lead to malnutrition and mercury poisoning. Use it sparingly as a treat.

Common Household Items That Are Dangerous
1. Houseplants
Lilies, philodendrons, aloe vera, and poinsettias are just a few common plants that can poison your cat.
2. Medications
Human pain relievers like Tylenol or Advil can be lethal to cats, even in small doses.
3. Cleaning Products
Surface sprays, bleach, and laundry pods should always be kept far from your cat’s food and water bowls.
4. Essential Oils
Oils like tea tree, peppermint, and citrus are toxic to cats and can cause breathing difficulties and organ damage.
Signs of Food Toxicity in Cats
If your cat has eaten something dangerous, watch for the following:
- Vomiting or diarrhea
- Lethargy
- Drooling
- Tremors or seizures
- Loss of appetite
- Pale gums
If you notice any of these signs, call your vet or an emergency animal hospital immediately. The ASPCA Animal Poison Control Center (APCC) is also available 24/7.
Safe Alternatives for Cat Treats
Instead of offering harmful human snacks, try:
- Commercial cat treats made with natural ingredients
- Small bites of cooked, unseasoned chicken or salmon
- Freeze-dried liver or shrimp
- A teaspoon of plain canned pumpkin for digestive health
Always consult with your vet before introducing new foods, especially if your cat has sensitivities or chronic health conditions.

“We used to give our cat milk as a treat until we noticed he was constantly gassy. Turns out, he was lactose intolerant. We switched to special cat milk, and he’s much happier.” – Michael T.
