Food allergies happen when the immune system of a cat misidentifies a protein as an invader instead of a food item, which triggers an immune response. This response could result in diarrhea and vomiting in some cats, while it might cause skin conditions and itchy ear or skin in others. <\/p>\n\n\n\n
Some unlucky cats will also have both gastrointestinal and skin symptoms. But bear in mind that food allergies also have to be distinguished from many other common causes of these problems.<\/p>\n\n\n\n\n\n\n\n
