Expressive language disorder is characterized by a child having difficulty expressing him- or herself using speech. The signs and symptoms vary drastically from child to child. The child does not have problems with the pronunciation of words, as occurs in phonological disorder .
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.
The squirrels do most of their feeding in the early morning and late in the day. An adult fox squirrel weighs less than two pounds and averages about twenty inches long from the tip of its nose to the tip of its tail. The tail, which is usually less than half of its total length, is a cinnamon color mixed with black.
