Short answer

Yes, that’s a common reaction. French fries are greasy and salty, which can easily upset a cat’s sensitive digestive system. Watch for signs like diarrhea, vomiting, or loss of appetite over the next day. If you see these, stop feeding any human food and contact your regular veterinarian for advice.
