I noticed TONS of people in my neighbourhood had this same type of tree than I finally found out they were weeping mulberry. So last fall as temps got colder and the trees were going dorment I went around collecting and picking the leaves from these trees. At this point I did'nt have my chameleon and had no idea when I would get him. So i ended up freezing the leaves. I finally got my cham and just bought him some silkies and they are devouring those leaves from the freezer. none of the tree have started to grow back their leaves yet this season.
