I don't think Casey cared enough to worry about the animals getting to her. Out of sight , out of mind. IMO of course!
No, she didn't care ~ and she didn't know that these animals would have come to her rescue, so to speak.
I firmly believe, that within a couple od days of Caylee being left there, that all kinds of animals had had their way and fill of her tiny body.
With it being in early summer, animals would have been feeding their young, so there would have been more of an animal population in those woods at that time.
From my experience of when our son lived in central Florida, there are all kinds of wild animals that most people don't realize are lving there.
Aside from raccoons, opposums, badgers, the gators {though I have not heard any neighbors comment on any gators being around there}; there are also wild boars, panthers, and, even bobcats.
Our son and wife had a female bobcat nest under their bedroom window one year and raise her young there for a few months.
They lived in a gated, golf club area, with lots of waterways and ponds, etc.
So, IMO, within a couple of days, parts of Caylee had already been fought over, and drug off to the "safety" of den areas or safe places, away from other foraging animals so that they could eat in peace.
The map clearly shows that of the remains area and where each peice was found.
And, she was not yet 3yrs old - Not more than probably, what, 40lbs if you give an extra poundage ~
That is not much of a meal for numerous animals and their young once they got ahold of her. {sorry for the visual and being so graphic}
And, certainly, what the animals didn't manage to drag off, the insects and bugs stayed put with what they already had and took care of the rest in little time also.
