I hang mine on a pulley system strung between a second story deck and a tree. The pulley allows me to pull in the feeders to fill them, then pull them back out to between the tree and the deck. The string is too thin for them to walk on, and the middle spot is too far for them to jump from tree or deck.
They still hang around on the ground underneath for the droppings, providing great entertainment for me and our 2 dogs when I let them out.
Not sure what either of them will ever do if they manage to catch one.
