Can Cats Eat Grapes?
No — grape toxicity is less documented in cats than in dogs, but because of the suspected kidney damage they are firmly treated as dangerous. Do not give your cat grapes or raisins.

Why are they risky?
In dogs, grapes are a well-known cause of acute kidney injury; in cats there are fewer reported cases, but that does not make grapes safe — cats simply show little interest in fruit, so fewer incidents occur. Veterinary toxicology references keep grapes and raisins on the dangerous list for cats too. Raisin cakes and pastries are the most likely route of exposure.
What to do if your cat ate grapes
Even for a small amount, check with your veterinarian and share when and roughly how much was eaten. If you notice vomiting, lethargy, or loss of appetite, go to the clinic without delay.
Watch for these signs
- Vomiting
- Lethargy, loss of appetite
- Changes in thirst or urination
If you notice any of these, contact a veterinarian without waiting.
Frequently asked questions
Do cats even like grapes?
Most cats are indifferent to fruit and cannot taste sweetness. The risk usually comes from mixtures like raisin cakes and cookies.
Is the toxic dose unknown for cats too?
Yes. Case data in cats is scarcer than in dogs; that uncertainty is a reason to give none at all, not a reassurance.
