Lectin is a protein and has the characteristic of sticking to the intestinal wall. Feeding lectin to a cat or offering non boiled beans often lead to digestive issues. Lectin interferes with nutrient absorption and causes digestive symptoms such as diarrhoea and vomiting.

Lectin poisoning occurs not only in cats but also in humans and can cause toxic symptoms such as severe vomiting, indigestion, and diarrhoea.

It is essential to boil the beans when feeding them. But it’s necessary to keep it small so that it doesn’t overcharge.
