Callum Higgins literally eats everything he can get his hands on, such as electrical wires, socks, pencils or his sister’s clothes and dolls. The disease he suffers from is called Pica and provokes the boy an unusual appetite for things, not for food. Callum also was caught while trying to chew on shoelaces and pieces of soap. “He constantly chews on things: cables, pens, socks, soap, anything. I am always worried,” says his mother. The woman is forced to lock the fridge using a chain to prevent the 10-year-old-boy from eating raw meat or frozen food.
