TJ's Household Haiku Challenge- Containers

Containers sometimes hold plants or objects, but the photo of a container I've chosen for this haiku blog hop at TJ's Household Haiku Challenge - Containers is one that holds a kind of mammal.  Although these mammals occasionally find their way inside a house, a public park put one of these containers on a long pole on their grounds.  The mammals, though feared by some, actually do a lot of good.
