The jump height directly depends on the physical characteristics of an animal and species. For example, the most common species in North America is the eastern gray squirrel. Adults reach 9-11 inches in length and can jump up to 9 feet forward and up to 4 feet up. Besides, do not underestimate their mental and acrobatic abilities. They can analyze the environment and find objects that they can push off to reach their goal in a few jumps.
