No. Pets should not have any alcohol whether wine, beer, or anything their owners like to consume. Depending on the amount ingested, alcohol poisoning can cause all sorts of problems in cats from vomiting and diarrhea to disorientation and difficulties in breathing, intoxication, severe liver and brain damage, coma, and death. Alcohol is very dangerous to cats because it’s easily absorbed by the body, and even small amounts like 1 teaspoon, can seriously hurt or kill your cat.
