Food intolerance in cats

Food intolerance is when a cat’s body is unable to cope with something they’ve eaten and they become ill. This is a common problem and may happen for different reasons. In rare cases, it can be serious, but more commonly, it’s a long-term problem that stops if the problematic food is no longer given.

Food intolerance can happen to any cat. It is different from food allergy because the immune system isn’t involved. It can be difficult to tell them apart though. Cats can become intolerant to something they’ve eaten for a long time, but it can also happen the first time they eat something new. Usually the symptoms are a digestive upset, but skin reactions are also common. Diagnosis is usually done with a strict diet for several weeks.
