what's the difference between squirrels and rats?
You can usually determine the type of rodent by the size of the feces. Mice feces will be no larger than a grain of rice. If you are looking at pellet-sized stool, chances are you have a rat or a squirrel on your hands. The difference between squirrel and rat poop can have a lot to do with shape and color. Because of their limited diets, squirrel droppings are usually lighter in color and have a wrinkled appearance. Rats will eat almost anything, and their fecal matter is often dark and oblong in shape. Depending on the species of rat, the droppings ends may be rounded or pointed.
