Her ride is a clear plastic food container mounted on an aluminium plate, wheels underneath, three copper bars at the front. Left bar for left, right bar for right, middle bar for straight ahead. A rat bouncing about when someone walks in could be excited about the drive, the cereal, or simply the company. Rats could walk directly to the Froot Loop, the efficient option, or they could turn away from the food, go to the car, and drive there instead. What a handful of rats can and cannot showThree rats is three rats.
