Make a noise like easy food and any critter that hasn't had too much pressure will usually come a running for lunch. Just figure what you would do if you needed food and had to find and then run down a cow usually, but you heard one moo like it was hurt. The race would be on and you would fight some for it if you needed to cause the expenditure of energy would still be less than how you usually found food. Or better go to main street and get a sign saying FREE LUNCH and see if you don't have more than a few people stop for that. If you have any rodent in distress sounds its going to be on.
