the eyes look like a scale and is usually located at the base of a growth. Catts usually have two "eyes" the leading growth comes from one eye and the second eye usually remains dormant. It is nature's way of providing continual growth if something should happen to the front lead. One way of making a clone of a Catt would be to cut through the rhizome. This should stimulate a "back eye" (meaning an eye on a back growth, behind your cut) to be stimulated to develop into a new lead. I have never really looked for them but the above info if from memory of a diagram I had seen in a book. I have taken back bulb divisions and they eventually develop a front lead, the majority of the time.
