Can Cats Eat Grapes
Sweet, juicy, and packed with nutrients, grapes seem like the ideal snack. However, what’s healthy for us isn’t always safe for our feline companions.
You may have heard warnings about dogs eating grapes and wondered, Can Cats Eat Grapes? Fortunately, most cats have little interest in fruit since, as obligate carnivores, cat need protein over sugary foods. Unlike human food, cat food is designed for their unique dietary needs. But what happens if a cat eat a grape that drops on the floor? Even a small amount of grape raisin can be dangerous.

Here’s what you should know about grape toxic risks, kidney disease, and why grapes are not a safe cat treat.
Can Cats Eat Grapes?
It is not recommended to feed grapes to your cat. While the risks of grapes are well documented for dogs, cases of cat eat grapes causing illness have been reported. Scientists are still investigating which specific compound in grape raisin is harmful to cats. However, the ASPCA Animal Poison Control warns that grape toxic effects can lead to kidney failure and kidney damage. Since the exact mechanism of toxicity remains unclear, it’s safest to assume that grape bad news applies to cats as well. To keep your feline healthy, avoid feeding grapes and stick to safe cat food options instead.
Are Grapes Bad for Cats?
Grape toxic effects are uncommon in cats, but they have been documented. Studies show that approximately 15% of dogs and cats that eat grape raisin may experience symptoms such as restlessness, reduced appetite, and vomiting. While kidney damage is rare, affecting less than 1% of reported cases, mostly in dogs, there are documented cases of kidney failure in cats. This suggests that even though the risk is lower, a cat small exposure to grape bad foods can still be dangerous.
The exact toxin remains unknown, but since both seeded and seedless grapes have caused toxicity, scientists believe it is not related to the seeds. Current research suggests a water soluble compound in the grape flesh is responsible. Some experts point to tartaric acid as a potential cause, as it is present in varying amounts in grapes and raisins. Given the potential risks, ASPCA Animal Poison Control advises against feeding grapes to cats, as even a single grape cause kidney damage. Instead, stick to safe cat food and avoid toxic cat treats.

Can One Grape Kill a Cat
Determining how many grapes or raisins a cat eat before experiencing toxicity is difficult, as some animals seem unaffected while others suffer severe reactions. However, the lowest documented amount of grape toxic exposure leading to kidney damage is 20 grams per kilogram of body weight for grapes and 3 grams per kilogram for raisins.
Since there are roughly four grapes in 28 grams, a 4.5 kg cat could develop symptoms of kidney failure after eating as few as 12 grapes. For raisins, which are more concentrated, the toxic threshold is even lower, around 30 raisins could be enough to cause kidney damage in a cat of the same weight.
Because raisins are simply dehydrated grapes, they contain a higher concentration of potentially harmful compounds, making them even more dangerous. Given the uncertainty surrounding the exact cause of toxicity, UK vets advise keeping both grape raisin away from cats. The safest approach is to feed grape free diets and avoid any human food that may pose a risk. If a cat small amount of grape bad food is ingested, seek veterinary advice or contact a UK animal poison helpline immediately.
