Deer repellent.....My standard poodle grows hair like crazy especially in winter. I clip him on a big comforter in the basement (outdoors in the summer), roll all the fur into the comforter and dump it around on deer sensitive perennials. He's black so eventually in good weather, I can turn it into the soil and it not only makes it a nicer color and loosens it, but deters deer all year long. Does not work for rabbits though. Now my neighbors take some for their own plants. We are having good luck with it.
