Just found long dark and stinky droppings within garage- could it be rats or something else?? please help identify
Answers:    If they're roughly a quarter to half an inch long, medication shaped and shiny I'd say it's particularly rats. You can usually tell rats and mice, not so much by the droppings as by the greasy track results they leave on their runs. They other follow the same pavement.
