Pet Poison Helpline notes grape poisoning is mainly reported in dogs and the toxin isn't confirmed. With no known safe amount in dogs, it's sensible not to risk it in cats.
No: toxic
No. Grapes and raisins are known to cause kidney failure in dogs, and while cases in cats are rare and less studied, vets advise keeping them away from cats too. If your cat ate any, call your vet.
This guide is general information, not a diagnosis. If your pet seems unwell, or you're worried, call your vet.
Why grapes are dangerous for cats
If your cat ate some
- Call your vet, an emergency clinic or a pet poison line straight away, even if your pet seems fine. Many poisonings are easier to treat before signs appear.
- In the US: ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661. Both may charge a consultation fee.
- Note what was eaten, roughly how much and when, and keep the packaging.
- Don't make your pet vomit unless a vet tells you to; it isn't always safe.
- Call your vet or a poison line for advice.
Signs to watch for
- Vomiting or diarrhoea
- Lethargy and not eating
- Drinking and peeing more, then less
Collapse, seizures, difficulty breathing or pale gums are emergencies: go to the nearest vet straight away.

Questions.
Are raisins worse than grapes?
Raisins are concentrated, so a small handful is equivalent to more grapes.
