Why

Grapes and raisins are known to cause acute kidney failure in dogs, and while research specific to cats is more limited, veterinarians universally advise against feeding them to cats. The toxic compound has not been identified, which means no safe amount can be established. Given the severity of the risk in animals, grapes and raisins should be treated as off-limits for cats entirely.

Portion Guidance

None. Avoid all grape products including raisins, grape juice, and foods containing grape extract.
