Grapes and Cats: Can Cats Eat Grapes?

Grapes pose a danger to cats because their kidneys might be damaged by eating too many grapes.

Can cats eat grapes? No, cats can’t eat grapes. Dried grapes can cause kidney damage when ingested often.

The resins could lead to nausea, diarrhea, and vomiting right away when consumed.

Can Cats Eat Grapes?

Cats should not eat grapes or raisins.

Many times, people give their pets grapes because they think that it is a healthy treat and/or snack for them to enjoy.

Grapes may be poisonous to cats, so don’t give them to your feline friend.

Even though grapes do contain some antioxidants, they do not provide any health advantages that cat chow does not already provide.

Cats who eat grapes run the risk of renal failure.

Feline renal failure can occur as a result of the poisonous chemical present in grapes and raisins. 

If your cat has eaten any grapes or raisins, please call your veterinarian immediately.

Do not wait to see if your cat will be okay.

Why Are Cats Dangerous To Grapes?

Can cats eat grapes? Most likely, they cannot because of the risks, but it’s best not to take chances with their health by feeding them something that isn’t necessary for a cat diet.

Grapes are bad news when ingested by pets, and while some people think grapes might be okay in moderation or only infrequently, cats shouldn’t eat grapes at all.

They don’t need a lot of carbs or sugar because cats are obligate carnivores.

What Are Grapes?

The fruit of the grapevine, botanically a berry, is a source of food and wine.

A pea-sized grape can be found in a cluster of grapes, which can be purple, yellow, green, or black in hue.

Fresh, juiced, fermented, and dried, they’re all readily available.

Grapes are also a popular, low-calorie snack and contain an antioxidant known as Resveratrol.

Grapes may be beneficial for people but can be dangerous to cats if ingested by them in large quantities or over time due to the toxin found within grapes: Glycoside Canthin-20, which is possibly carcinogenic.

What Happens If A Cat Eats Grapes?

If a cat eats grapes, it can get very sick.

In addition to hyperactivity and vomiting, these are the most common symptoms of grape poisoning in cats: 

  • Lethargy
  • Reduced urination
  • Abdominal pain
  • Loss of appetite

The other symptoms generally appear within a day or two.

One of the more dangerous side-effects of eating grapes is renal failure, which can be deadly for your cat.

So, while a single grape won’t kill them, it’s still best to keep grapes and cats far away from each other.

  • Grapes can cause renal failure in cats.
  • This is a serious health problem for cats and can be deadly.
  • Keep your grapes and your cats separate!

What to Do If Your Cat Eats Grapes?

  • Stop feeding them grapes.
  • Make sure they are safe and sound.
  • Call a veterinarian as soon as possible. 

Grapes can be deadly to cats if consumed in large quantities or over an extended period of time.

If your cat ate any grapes, you should expect them to be alright if they only ate a few grapes and were treated quickly afterward.

Their therapy was delayed, which may have caused irreversible kidney damage that could have been deadly.

Grapes are dangerous for cats because of the toxin found in them called “oxalate.”

Different types of grapes contain different levels of toxins.

The more common green grapes have a lower level of toxin than the red or purple grapes.

If your cat ate any type of grape, take action promptly and call a veterinarian.

It is important to note that not all cats are affected by this toxin.

Some cats may show no signs of being poisoned, while others may vomit, have diarrhea, become lethargic, or have seizures.

If you have any doubt about the safety of your cat eating grapes, call your veterinarian immediately.

A single grape can cause stomach issues and even allergies in cats that ingest it.

They may also become exhausted or show signs of renal failure if many grapes are consumed over an extended period of time.

Grapes are a type of fruit that is generally safe for cats to eat, but they should not consume too many grapes or raisins as these can be toxic.

What Fruits Can Cats Eat?

There are a few fruits that are generally safe for cats to eat, including bananas and pineapples. Grapes aren’t on this list, though, because they can harm your cat.

The reason why grapes are bad is because of their high amount of sugar content – similar to candy which most people know isn’t good for them either! 

Here are some other fruits that cats can eat:

  • Pineapple

Pineapple contains high levels of zinc and folate, which are beneficial to your cat’s digestive and immunological systems.

  • Mango

This fruit is a good source of vitamins A, B-complex, C, and fiber. 

  • Apple

Small slices of apple with meat and skin can be fed to cats, as the meat and skin contain phytonutrients, pectin, vitamin K, and vitamin C. 

  • Watermelon

Though it’s generally safe for cats to eat watermelon, you should always remove the rind or seeds before feeding the watermelon to them. 

  • Banana

A good source of dietary potassium and vitamin C, bananas are a healthy snack for cats.

So as you can see, there are plenty of fruits that your cat can enjoy without having to worry about any harmful side effects!

Just be sure to avoid giving them grapes and always remove the rind or seeds from other fruits before feeding them to your pet.

If you are ever unsure, it’s always best to speak with your veterinarian about what foods are safe for your specific cat. 


Grapes are not known to be harmful to cats, but it is still not a good idea to give them your feline buddy.

A ripe grape from your fruit dish is unlikely to pique the curiosity of most cats.

The most important thing to avoid is providing your cat grapes in a concentrated form, such as juices, currents, or raisins which can be toxic for cats and humans alike.
