Grapes and raisins are harmful to dogs and cats. The most danger is acute renal failure (kidney failure) due to difficulty urinating (oliguria). Vomiting and diarrhea usually appear within a few hours and after swallowing for 24 hours. Things in the vomit and feces may contain fragments of grapes or raisins. Other symptoms such as dehydration, causing lethargy and weakness.


Grape cultivation began about 6,000–8,000 years ago.

It shows that dogs and cats are not able to filter toxins by themselves, which is still unclear what kind of toxins in the grapes and raisins are harmful to dogs and cats.
