Are Grapes and Raisins Toxic to Cats?
Grapes and raisins cause well-documented kidney failure in dogs. In cats, research is less clear — but vets treat every grape exposure as an emergency. Here is why caution matters and what to tell your vet.
Treat every exposure seriously
There is no known safe dose for grapes or raisins in cats. Do not wait to see if your cat seems okay.
Why grapes and raisins are a concern for cats
The exact toxic compound in grapes is still unidentified, but the effect on kidneys is well established in dogs. Case reports in cats exist, and because cats hide illness well, prevention and prompt action are essential.
Common sources of exposure
- Fresh grapes from a fruit bowl or lunchbox
- Raisins in cakes, mince pies, and cereal
- Sultanas in hot cross buns and baking
- Grape juice and wine spills
What to tell your vet
Provide your cat's weight, how many grapes or raisins were eaten (or best estimate), and when it happened. Mention any vomiting or changes in drinking or urination. Your vet may recommend inducing vomiting, activated charcoal, IV fluids, and kidney monitoring.
