Can Cats Eat Grapes? Here’s What You Need to Know

As a cat owner, it’s understandable to be curious about what you can and cannot feed your furry friend. One of the questions that come up quite frequently is whether cats can eat grapes.

To put it simply, grapes are not recommended for cats. While they may seem like a harmless snack, there are several reasons why you should avoid giving them to your cat.

The Dangers of Grapes

Grapes and raisins can cause kidney failure in dogs, but the effect on cats is still unknown. However, certain compounds found within grapes that have been known to affect dogs could potentially harm cats as well. For example, grape toxicity in dogs has been linked to an unknown substance present inside the fruit known as tannins or oleanolic acid.

The exact amount required for intoxication varies according to size and weight; however, even small amounts could lead to negative side effects such as vomiting and diarrhea.

Symptoms of Grape Poisoning

If your cat accidentally ingests grapes or raisins (which contain higher concentrations), keep an eye out for symptoms like:

– Vomiting
– Diarrhea
– Lethargy
– Decreased Urination
– Abdominal Pain

These signs usually require immediate veterinary attention since they could indicate potential kidney damage caused by grape poisoning.

Other Human Foods Cats Should Avoid

While we’re on the topic – there are other human foods besides grapes that felines shouldn’t consume too! Here’s a quick list:

1) Chocolate: It contains caffeine-like substances called methylxanthines which overstimulate their nervous system.

2) Onions/Garlic: They contain thiosulphates which cause digestive problems when ingested in large quantities.

3) Alcohol: Even small amounts can severely impact their liver and brain functions.

4) Dairy: Cats do not have enough lactase in their system to break down lactose, leading to diarrhea and vomiting.

5) Fatty Foods: They can lead to pancreatitis or inflammation of the pancreas.


In summary, cats should avoid eating grapes due to its potential toxicity. While there are plenty of human foods that cats can eat safely, it’s best always to research what you’re feeding them before giving them any treats from your plate. Stick with a balanced diet designed for their specific nutritional needs and consult your veterinarian if you’re unsure about anything. Trust us; they’ll appreciate it!
