Not all animals seem to grasp the basic principles of playing with a ball, and this young deer appears to be one such animal.
We can’t figure out if it’s terrified of the ball, has horrible aim, or is simply confounded by the small rubber sphere under its feet. Perhaps it’s just doing what deer do: being flighty and generally unpredictable.
At any rate, the fawn appears to be tame and is likely being rehabilitated. Deer who lose their mothers at a young age are often turned over to human caretakers before they are released back into the wild.
