You recognize the different squirrel poop types because the gray squirrel is a bit larger than the red squirrel. Rat poop tends to be blacker and darker than squirrel poop, which can be tan or red in color. Squirrel scat is always found in clusters as these animals are more discreet about their excretion habits and look for remote corners to do the deed. What is the overall shape of the pellets? High-moisture foods may result in clumpy or soft, spindle-shaped feces, while low-moisture foods may result in feces with pointed ends like deer feces.
Rat droppings are pointier, squirrel droppings rounder. Squirrel poop has a smooth texture while rat and mice poop have a grainy texture. The main difference between their poops is the size; they will both leave droppings that look to be the same shape (about the shape of rice). What color is it? Squirrel feces may also be spindle-shaped or they may appear clumped, depending primarily on the moisture content of their food source. If you are dealing with a squirrel it will be shaped more like a barrel whereas what a rat leaves behind tend to be thinner and longer. The most common squirrels that can cause you a problem are the red and the gray squirrel. Rat droppings are spindle-shaped.
