Short answer

Yes, this is an urgent situation. Even a single raisin can be toxic to cats and cause acute kidney failure, regardless of their size. Contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately for guidance. Do not wait for symptoms to appear.

Raisins — Food safety facts

Do not feed · Cats · full breakdown on the linked food page

Toxic, like grapes — a small amount can cause acute kidney failure. Even one raisin for a small dog deserves a vet call.

Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.

Raisins should not be given to cats at all. Even a small amount can do harm, so there is no portion small enough to be safe.

Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.

Why these cautions matter

Grapes and raisins are linked to kidney failure in dogs, and no safe amount is reliable — some pets react after only a few.
