answer:No meat products or by-products (bones, skin, fat), ditto for chicken and fish. Fireplace ashes are wonderful for flower beds. I would bag and toss the cigarette butts in the trash. Egg shells, coffee grounds, loose tea, tea bags without the staples,veggie scraps, shredded newspaper (only black and white) are the obvious good guys. You do not want to tempt the raccoons; and cigarette stubs are just plain nasty.
