While cats and humans share some dietary needs like water and protein, their nutritional requirements diverge significantly. Many human foods can be toxic to cats, leading to digestive problems, vitamin deficiencies, anemia, and even life-threatening conditions. It’s vital to understand What Food Is Poisonous For Cats to protect your feline friend’s health.

11 Dangerous Foods: What Food Is Poisonous for Cats?
Here’s a detailed list of foods that can be harmful or even fatal to cats:
1. Alcohol
Alcohol, found in beverages like wine and beer, and even in some foods, is extremely toxic to cats. It can cause diarrhea, vomiting, breathing difficulties, tremors, coma, and death. Even small amounts can be lethal. Seek immediate veterinary help if you suspect your cat has ingested alcohol.
“Just two teaspoons of whisky can cause a coma in a 5-pound cat, and one more teaspoon could kill it,” reports Fetch by WebMD.
2. Chocolate
Chocolate contains methylxanthines, specifically theobromine and caffeine, which are highly toxic to cats. These compounds are found in cacao seeds and can cause a range of symptoms associated with chocolate poisoning.
Symptoms of chocolate poisoning include:
- Diarrhea
- Vomiting
- Weakness
- Rapid breathing
- Elevated temperature
- Muscle rigidity
- Increased reflex response
- Seizures
- Cardiac arrest
- Coma
Chocolate Toxicity Levels in Cats (8 lb. Cat)
| Type of Chocolate | Minimum Toxic Amount |
|---|---|
| Milk Chocolate | 1.14 oz. |
| Dark Chocolate | 0.5 oz. |
| Semi-Sweet Chocolate | 0.5 oz. |
| Baking Chocolate | 0.2 oz. |
| White Chocolate | N/A (but still not recommended) |
Consult your veterinarian immediately if your cat consumes any amount of chocolate, as these are approximate amounts from The Spruce.
3. Dog Food
While occasional nibbles of dog food might not be immediately harmful, it should never be a substitute for cat food. Cats require specific nutrients like high levels of protein, vitamins, and fatty acids, which are adequately provided in cat food. A steady diet of dog food can lead to severe malnourishment.
4. Grapes & Raisins
Grapes and raisins contain an unidentified toxic substance that can cause kidney failure in cats. The ASPCA advises pet owners to avoid feeding these fruits to their cats entirely.
5. Liver
Excessive consumption of liver, or liver-containing products, can lead to vitamin A toxicity. This condition can severely affect a cat’s bones, causing deformities, bone growths, and osteoporosis, potentially leading to death in severe cases.

6. Milk & Dairy Products
Many cats become lactose intolerant as they mature, making it difficult to digest dairy products. High or frequent consumption of lactose-containing dairy can result in gastrointestinal pain and diarrhea.
7. Onions, Garlic & Chives
Onions can damage a cat’s red blood cells, causing weakness, shortness of breath, and anemia. Garlic, which is five times more potent than onions, and chives can cause similar health issues. Avoid feeding your cat onions, garlic, or chives in any form: powdered, cooked, raw, or dehydrated.
8. Raw/Undercooked Meat, Eggs & Fish
Raw meat, fish, and eggs can harbor bacteria like Salmonella and E. coli, harmful to both humans and immunocompromised pets. Raw eggs also contain an enzyme that inhibits the absorption of biotin (a B vitamin), leading to skin and coat problems. Raw fish contains an enzyme that destroys thiamine, another essential B vitamin, potentially causing neurological problems, convulsions, or coma.
Properly prepared raw meat-based diets, specifically formulated for pets, are regulated to minimize harmful bacteria. Cooked eggs, however, can be a healthy treat in moderation.
9. Canned Tuna
A steady diet of canned tuna can cause malnutrition in cats because it lacks essential nutrients. Excessive tuna consumption can also increase the risk of mercury poisoning. If your cat enjoys the taste of tuna, opt for cat food made with human-grade tuna, which is formulated to provide the necessary vitamins and minerals.

10. Uncooked Potatoes & Tomatoes
Raw potatoes and tomatoes can cause gastrointestinal distress in cats. While cooked potatoes and tomatoes are generally safe, green potatoes (cooked or raw) can lead to cardiac issues, hallucinations, and paralysis. Keep green potatoes away from your feline companion.
11. Yeast Dough
Yeast dough can rise and cause gas accumulation in a cat’s digestive system, leading to bloating and pain. In severe cases, the stomach may twist, creating a life-threatening emergency.
Recognizing Toxicity: What Food Is Poisonous for Cats and What Are The Symptoms?
The most common signs of toxicity in cats include:
- Breathing problems
- Confusion
- Coughing
- Depression
- Diarrhea
- Dilated pupils
- Increased thirst and urination
- Upset stomach
- Seizures
- Shivering
- Skin irritation

What to Do if Your Cat Eats Something Toxic
If you suspect your cat has ingested something toxic:
- Watch for Symptoms: Closely monitor your cat for any unusual behavior or signs of distress.
- Call Your Vet: Contact your regular veterinarian or an emergency vet clinic immediately.
- Bring Samples: If possible, collect vomit or stool samples to bring to the vet for analysis.
According to 1-800-PetMeds, about 25% of poisoned pets recover within two hours. Pets can often be treated at home under veterinary guidance or with advice from the ASPCA’s Poison Control Center.
Safe Human Foods for Cats: What Food Is Poisonous for Cats vs. What is Safe?
While many human foods are dangerous, some are safe for cats in moderation:
- Cheese: Cheese can be a good source of protein as an occasional treat. However, due to lactose intolerance, give it in very small amounts infrequently.
- Cooked Eggs: Cooked eggs are an excellent source of protein. Always ensure they are cooked to avoid bacterial contamination.
- Fish: Rich in omega-3 fatty acids, fish can help with arthritis, kidney disease, and heart disorders. Offer canned or cooked fish as an occasional treat, avoiding raw fish.
- Meat: Cats thrive on meat-based diets. Choose wet or dry food that is high in protein, high in moisture, moderate in fat, and low in carbs, or a properly balanced and prepared raw or cooked diet.
Understanding what food is poisonous for cats is essential for every cat owner. By being informed and cautious, you can ensure your feline companion lives a long, healthy, and happy life.
