There are two c’s in raccoon.  I just thought you should know.  I mean, good spelling skills are not necessarily a measure of intelligence.  My father is a brilliant and world-renowned (in certain circles) scientist, and last I checked he still spells “cheese” with a “z”.  But if you’re giving instruction on writing, and more specifically editing, I think it would be nice if your example did not include a paragraph in which raccoon is spelled incorrectly eight times.  Also, you use ”it’s” for “it’s jumping over the fence” and “its” for “its tail is stuck between the planks”.  I’m just saying.
