Strange droppings in yard

   I found these strange droppings in my yard today, I live inner city and I immediately panicked as I thought rats. These droppings have only appeared over the past day or so. I checked them with a friend who is a bit of a rat expert and she said she’s never seen rat droppings like this before (pet or street rats). 

Theyre quite long and windey, does anyone have any idea what they are? Theres absolutely loads of it.
