Can cats eat grapes?
Grapes and raisins are linked to acute kidney injury in pets. Avoid entirely.
Portion: None. There is no known safe amount.
The short answer
No. Grapes and raisins are on the ASPCA's list of foods to keep away from pets. They're best known for causing acute kidney failure in dogs; feline cases are reported less often, but the risk is taken seriously and no safe dose is known. If your cat has eaten any grape or raisin, call your vet or a pet poison hotline straight away.
Why it’s dangerous
Tartaric acid has been identified as the likely toxic compound in dogs, which can damage the kidneys. Sensitivity varies unpredictably between individuals, so even a small amount is treated as potentially dangerous. Cat-specific data are limited — which is exactly why vets recommend zero exposure.
How to keep your cat safe
- Do not feed in any form: fresh, dried, juice, or baked into goods.
- Watch for raisins in bread, cookies, cereal and trail mix.
- Store grapes out of reach — cats bat them around like toys.
Signs of trouble
- Vomiting or diarrhoea within hours
- Lethargy, weakness
- Loss of appetite
- Drinking and urinating more, then less
- Abdominal pain
