Drooling, vomiting, weakness. Vet if more than a lick.
If your cat has eaten grapefruit, don't wait for symptoms.
Call your vet, or in the US the ASPCA Animal Poison Control Center (888-426-4435) or Pet Poison Helpline (855-764-7661), 24 hours a day. Have the amount, the time and any packaging ready.
