@ai6yr They are very clever and stronger than they should be. They figured out how to open the side latch and stole all the suet. So I strapped it closed with some coat hanger. Then they pulled the curlicues up and stole all the suet. Added more coat hangers to block the areas where they could get the suet. They still keep trying! They get what they can nibble, which is fine. The birds chase them off when they want some.
