Actually, some people leave the cup in, and dont feed them for 2-3 days. They get hungry, and eventually eat from the cup. Then they learn, "Thats where to get food."

EDIT: Thanks Tiff! I just realised the cup is on the floor.
Put it near a favourite branch like Miss Lilly said.
What condition is it in? I would love it. Unfortunatley, It would cost quite a lot. Plus, Idk if its legal to bring BTS's across the border.
