No. Evidence in cats is thinner than in dogs, but the safe answer is to treat grapes as poison.

Why it’s a problem

In dogs, grapes and raisins cause sudden kidney failure, and the toxic compound remains unidentified. Poisoning reports in cats are fewer, but absence of evidence is not evidence of safety — with no known safe dose, vets advise treating any grape ingestion in a cat as serious.

How to serve it safely

Never offer grapes, raisins, sultanas or currants in any form, and keep trail mix, granola bars and fruit bowls out of feline reach.

Warning signs to watch for

Vomiting, diarrhea, lethargy, loss of appetite, increased thirst and reduced or absent urination within a day.

When to call the vet

See a vet immediately if grapes or raisins were eaten — early decontamination and fluids protect the kidneys.

Common questions

How many grapes would hurt a cat?

Nobody knows, and that is the problem. Dose-response is unpredictable even in dogs, so any amount is treated as an emergency.
