Lets not forget the motorized rat decoy. Just stop by your local Adult entertainment store and buy a couple small "aa" toys. Insert the "motor" into the toilet paper stuffed rat and toss on the ground. When it is flopping around and buzzing, the rest will come running. If you don't feel like using stuffed decoy, just use your first killed and cleaned rat of the day and stuff the "motor" into that. Then you have natural scent too!
