2-Grapes and Raisins
Even a small amount of grapes and raisins can cause your cat to become ill — they can even lead to rapid development of kidney failure. Within 12 hours of ingestion, vomiting sometimes occurs. Other signs that can show up within 24 hours include lethargy, diarrhea, reduced appetite, abdominal pain, decreased urination and abdominal pain.
Although it isn’t clear why, grapes and raisins can cause kidney failure in cats, and even a small amount can make a cat ill. Repeated vomiting and hyperactivity are early signs. Although some cats show no ill effects, it’s best not to give your cat any grapes and to keep grapes and raisins off countertops and other places accessible to your cat.
