Dr. Tina’s Answer: No.

General Information: Dogs are the only species in which toxicity has been well described to date. It is uncertain whether or not it is toxic in cats and ferrets as there have only been anecdotal reports and data are lacking to confirm this. To err on the side of caution, avoid feeding your cats/ferrets any grapes/raisins.

What does it do? The toxicity damages the kidneys leading to severe Kidney Failure and death.

How does it cause Kidney Failure? The mechanism of toxicity are currently unknown. Amounts (estimated as low as 1/3 oz of grapes per pound body weight and 0.05 oz of raisins per pound of body weight) and type of raisins or grapes to cause toxicity is variable.

The Signs of Toxicity: Signs can develop within 24 hours to several days: Vomiting, diarrhea, inappetance, lethargy, abdominal pain, dehydration, decreased urine production to no urine production. *NB: If you know your pet has ingested grapes/raisins, it is always better to have him/her treated rather than wait for these signs to develop!!

Immediate Action: Seek veterinary assistance and induce vomiting.

Veterinary Care: Induction of vomiting, gastric lavage may be performed, and activated charcoal administered. Supportive care for monitoring and treatment for kidney failure with hospitalization, intravenous fluid therapy, diet change and medications will be initiated.

Prognosis: Variable and can depend on how quickly supportive care is initiated.
