Can cats eat grapes?
Grapes cause kidney failure in dogs. For cats there are only isolated reports (Merck: anecdotal, one case), but Cornell lists grapes as toxic to cats – so don't give any.
Did your cat eat some?
Call your vet or an emergency vet clinic right away, even if your cat seems fine. Tell them what your cat ate, how much and when.

No – toxic. Grapes can cause acute kidney failure in dogs. It is impossible to predict which dogs are affected or how many grapes it takes; no amount has been proven safe.
