Raisins (and grapes) are considered toxic to cats and should never be given on purpose.

Quick Scoop

  • Raisins and all grape products (grapes, currants, sultanas) can cause serious illness and even acute kidney failure in cats.
  • Even a small amount may be dangerous, and there is no proven “safe” dose, because some cats are more sensitive than others.
  • If a cat may have eaten raisins, vets recommend contacting an emergency vet or pet poison service immediately , even if the cat still looks normal.

What can happen to a cat?

Raisin toxicity in cats can start with gastrointestinal upset and progress to kidney damage. Symptoms may appear within hours but kidney problems can develop over a day or more.

Watch for:

  • Vomiting, diarrhea, drooling, or not wanting to eat.
  • Lethargy, weakness, dehydration, or drinking/peeing changes that can signal kidney trouble.

What to do if your cat ate raisins

Time is critical, so home “wait and see” is risky. Do this:

  1. Remove any remaining raisins or raisin-containing food so the cat cannot eat more.
  1. Call your veterinarian or an emergency clinic right away; describe how many raisins, when, and your cat’s weight.
  1. Follow veterinary instructions; they may recommend inducing vomiting and doing blood/urine tests and fluids to protect the kidneys.

Do not try home remedies like hydrogen peroxide or salt without vet guidance, as these can cause other harm.

Prevention and safe treats

Because even tiny amounts in baked goods or snacks can be a problem, all raisin and grape products should be kept strictly out of reach of cats. This includes items like raisin bread, trail mix, granola bars, and some cereals.

Safer treat ideas:

  • Vet-approved commercial cat treats in moderation.
  • Plain cooked meat (no seasoning, no onion/garlic) as an occasional small treat, if your vet agrees.

Bottom line: if you’re ever wondering “are raisins toxic to cats,” treat them as dangerous and act fast if your cat gets into any.
