Cats are beloved family members for many people, and it’s only natural that we’d want to share some of our food with them from time to time. However, not everything that is harmless or even healthy for humans is safe for cats. Some foods can be toxic and even fatal for our furry friends. Therefore, it’s essential to know which foods you should never give to your cat. 

1. Chocolate and Caffeine 

Chocolate, especially dark and baking chocolate, contains theobromine and caffeine. Both substances can be toxic to cats, leading to a rapid heartbeat, trembling, and in severe cases, even fatal poisoning.

2. Onions and Garlic 

Both raw and cooked onions and garlic can be harmful to cats. They contain compounds that can destroy red blood cells, leading to anemia. 

3. Alcohol

Alcohol affects a cat’s brain and liver similarly to how it affects humans. However, cats need only a very small amount to get poisoned. Symptoms can include vomiting, breathing difficulties, coma, and in the worst case, death. 

4. Grapes and Raisins 

It’s somewhat puzzling, as the exact toxicological reason why these fruits are so harmful to cats is not fully understood. Still, studies and clinical observations have shown that consuming even a small amount can lead to severe health issues. 5. Symptoms of poisoning can range from vomiting and diarrhea to lethargy and depression. In the worst case, consumption can lead to acute kidney failure, a severe condition that can be fatal without timely veterinary treatment.

5. Bones and Raw Meat 

Bones can cause internal injuries, and raw meat might be contaminated with bacteria like salmonella, leading to serious digestive issues. 

6. Milk and Other Dairy Products 

Many cats are lactose intolerant, meaning they can’t properly digest lactose. This can lead to diarrhea and other digestive problems.

7. Raw Egg 

Raw eggs can increase the risk of salmonella or E. coli poisoning. They also contain a protein called avidin, which inhibits the absorption of biotin (a B-vitamin), potentially leading to skin and coat problems. 

8. Xylitol

This artificial sweetener, found in many sugar-free foods and chewing gums, can cause a rapid insulin release in cats, leading to hypoglycemia (low blood sugar). 


It’s essential to emphasize that this list is not exhaustive. When in doubt, it’s always better to be safe and feed your cat food specifically made for them. If you suspect that your cat may have ingested something toxic, you should immediately see a veterinarian. Prompt action can be life-saving in such cases.
