What Foods Are Poisonous to a Cat? (Helpful Tips)

There are many foods that are poisonous to cats, and it’s important to be aware of which ones to avoid feeding your feline friend.

If cats eat poisonous food, they could become very ill and even die. Symptoms of poisoning can include vomiting, diarrhea, loss of appetite, increased thirst, drooling, seizures, and coma.

It is important to take a cat to the vet immediately if it is suspected of consuming a poisonous substance.

Foods Your Cat Should Never Eat

Some of the most common poisonous foods for cats include:

Onions and Garlic

Onions and garlic are members of the Allium family and are toxic to cats. Eating even small amounts of onions or garlic can cause damage to a cat’s red blood cells, leading to anemia. Eating large amounts can be fatal.


Chocolate contains theobromine, which is toxic to cats. Depending on the type of chocolate, the amount ingested, and the size of the cat, chocolate can cause vomiting, diarrhea, seizures, and even death.

Grapes and Raisins

Grapes and raisins have been linked to kidney failure in cats. While the exact cause of this reaction is unknown, it is recommended to avoid feeding cats grapes and raisins.

Raw meat

Raw meat can contain bacteria that is harmful to cats. It’s best to cook meat before feeding it to your cat.


Milk is not easily digested by cats, and can cause vomiting and diarrhea. It’s best to avoid giving your cat milk altogether.


Alcohol is extremely toxic to cats and can cause vomiting, diarrhea, decreased coordination, central nervous system depression, difficulty breathing, tremors, abnormal blood acidity, coma, and even death.


Caffeine is found in coffee, tea, energy drinks, and some sodas. It can increase a cat’s heart rate and cause vomiting, restlessness, and hyperactivity. In high amounts, caffeine can be fatal.

Human Medications

Human medications, such as painkillers, cold medicine, and vitamins, can be toxic to cats. Always check with your veterinarian before giving your cat any human medications.
