The answer to the question is no, as grapes and raisins cause kidney failures in cats. There are a lot more than grapes and raisins to look out for when it comes to food you should avoid giving your cat however, so keep on reading to learn more.Cats are very different from humans and even dogs when it comes to what they can and can´t eat. Cats are obligate carnivores, which means that they have a strictly meat based diet. The best practice is to keep your cat´s diet and food completely separate from yours.


If your cat starts to display symptoms of illness or abnormal behavior after having eaten something it shouldn’t, call your veterinarian immediately or call the hotline at 1-855-213-6680 (in the US) for assistance if your vet is unequipped to deal with the situation.

Below we have compiled a list of dangerous food for your cat and the potential consequences for eating them and the symptoms associated with eating toxic food. It is always better to be safe than sorry, so if you suspect your cat has eaten something it shouldn’t or notice unusual behavior or symptoms, seek help right away.

Food That Is Okay (In small amounts)

Cooked Boneless Meat Okay, as a treat.

Brown RiceOkay, as a treat.

Dog FoodOccasionally, but not recommended.

Some dog food now and then does not harm your cat. However, it is NOT a substitute for cat food as dog food lacks some vitamins and fatty acids that a cat needs in their diet. As such your cat would become severely malnourished if it were to eat only dog food.


Cats can become addicted to tuna whether the tuna is made for human or feline consumption. An occasional piece of tuna is not harmful to your cat; however, it lacks all the nutrients a cat needs. An overconsumption of tuna by your cat can lead to mercury poisoning, so be careful not to leave it unattended while preparing your tuna salad.

Liver Okay in small amounts.

Giving your cat some liver is okay in small quantities, but ingesting too much of it can cause vitamin A toxicity. Vitamin A toxicity is a serious condition that can affect your cat´s bones. Symptoms include deformed bones, bone growths of elbows and spine, osteoporosis and death.

Raw Meat – Okay, but can be dangerous.

Raw meat is part of a cat´s natural diet, however eating raw meat can cause food poising from bacterias like E. coli and salmonella. Proper sourcing of the meat is important.

Food Your Cat Shouldn’t Eat

Onions – Never

Onion, in all forms, powdered, raw, cooked or dried can break down a cat´s blood red cells, leading to anemia.

Garlic – Never

Digesting garlic will cause gastrointestinal upset for your cat.

Chives – Never

Digesting chives will cause gastrointestinal upset for your cat.

Alcohol – Never

Alcohol has the same harmful effect on a cat´s liver and brain as it has on humans. The big difference is that it takes far less of it to do serious damage.

According to PetMD two teaspoons of whiskey is enough to cause a coma in a 5-pound cat, and one more teaspoon could be fatal. The higher the percentage of alcohol, the more severe the symptoms, and consequences.

Grapes and Raisins – Never

The reason is unknown, but grapes and raisins can cause kidney failure in cats and should never be given as a treat. A small amount will make your cat ill and cause vomiting and hyperactivity.

Caffeine – Never

Caffeine in large enough quantities is lethal to cats, and there is no antidote. Symptoms of caffeine poising include restlessness, rapid breathing, heart palpitations, muscle tremors, and fits.
Caffeine is in a lot of products for humans such as some painkillers, energy drinks, cocoa, sodas, and chocolate. It is, consequently, crucial that you keep your cat away from products like these

Chocolate – Never

Chocolate can be lethal for cats. The reason for this is that chocolate (all chocolates, even white chocolate) contains theobromine, which is a toxic agent to cats which can cause a host of symptoms such as abnormal heart rhythm, tremors, seizures, and death. As mentioned, chocolate also contains caffeine which is also dangerous for your cat.

Raw Eggs – Never

Eating raw eggs can cause food poising from batteries like E Coli and salmonella. It can also interfere with the absorption of the B vitamin biotin. A deficiency of biotin leads to problems with your cat’s coat and skin problems.

Milk Or Other Dairy Products – Never

Even though many cats are depicted in cartoons as avid milk drinkers, most cats are in fact lactose intolerant, as such digesting dairy products can upset their stomach and cause diarrhea.

Yeast Dough – Never

It’s great when our yeast dough swells and big becomes nice and big when we are baking. It’s not so good when the same things happen inside your cat’ stomach.

The swelling of the dough inside the stomach can stretch the abdomen and cause severe pain. Yeast dough also produces alcohol when fermenting, which could cause your cat to get alcohol poisoning.

Raw Fish – Harmful in large amounts

An enzyme in raw fish destroys thiamine, which is an essential B vitamin [1] in your cat’s diet. A lack of this vitamin can cause severe neurological problems and lead to convulsions and coma.

Bones or Fat Trimmings – Never

Bones can splinter and obstruct or cause lacerations to your cat’s digestive system.

Human medications – Never

A cat´s physiology is different from a human’s, and therefore the medications made for humans should be taken by humans, not by cats or any other animals. Poisoning from consuming a drug made for humans is one of the most common causes of poisoning in cats. Just as you would for your children, keep them stored away in a place where your cat or your kids can’t reach them. Do not give your cat any over the counter medicine unless advised to do so by your vet

Tobacco – Never

Contains nicotine, which affects your cat´s nervous and digestive systems Symptoms include rapid heart beat, collapse, and death.

Macadamia Nuts – Never

Macadamia nuts have been found to contain an unknown toxin which can affect your cat´s nervous and digestive systems as well as muscles.

Baby Food – Never

Since many Baby Food blends contain onion powder which is as mentioned toxic and potentially deadly for cats, you should never let your cat eat these.

Marijuana – Never

Digestion of Marijuana depresses your cat’s nervous system and cause vomiting and changing heart rate.

Persimmons – Never

Persimmon seeds can cause intestinal blockage and enteritis.[2]

Candy and Gum – Never

Candy, gum, toothpaste, baked foods and some diet foods are sweetened with Xylitol.Xylitol can lead to liver failure in your cat. Symptoms soon after ingestion include vomiting, lethargy, and loss of coordination. Your cat may also experience seizures. Liver failure can occur just a few days after ingestion.

You Can Be Vegan, Your Cat Can’t.

Plants and vegetables do not belong in your cat’s diet, in fact, ingesting them can cause harm to your cat, or even worse, be lethal.

Cats do not usually seek out or eat plants or vegetables by themselves, but a young curious kitten might want to sample the plants or vegetables around him or her, especially if it is an indoor cat that gets bored with being confined to a limited space such as an apartment.

Outdoor cats might accidentally ingest things like plant seeds during the grooming of their fur, causing harm to them. Most cats do however like to nibble on grass or some herbs that may cause them to vomit afterward as a method of cleansing their stomachs.
