What the sources say
- According to the ASPCA, the toxic part may be tartaric acid: dogs can’t process it, so grapes and raisins can damage their kidneys.
- None of the sources we read gives a safe amount.
- The evidence is about dogs. The sources say nothing about cats: keep grapes away from them too.

What to do now
- Call your vet or the nearest emergency vet now, even if your pet seems fine: signs can take hours or days to show.
- Move your pet away from what it ate and take away what's left. If some is still in its mouth, offer a toy so it lets go.
- If the substance is on its fur or skin, wash it off with a mild shampoo and water, then rinse well and dry.
- Keep the packaging, the label or a piece of the plant, or take a photo, and bring it with you.
- Tell the vet what your pet swallowed, roughly how much and when.
What not to do
- Don't make it vomit unless the vet tells you to.
- Don't use salt water: it's extremely dangerous.
- Don't try to treat your pet yourself or give it medicines: some medicines for people and other animals are poisonous to pets.
- Don't wait for signs to appear.
