you would be surprised what animals will eat, My dog for example used to eat matchbox cars and nail polish remover.....and both of them do not seem like something that you would be readily attracted to eating lol
I know there was a problem with people in my hometown leaving used anti-freeze in milk jugs outside on the curb to be recycled cause the animals would get into them and drink it....apparently anti-freeze is the equivalent of a tasty drink to animals even though it can kill them
