I would assume any parts that apply to animals born here would also apply to animals that live here even if they were born abroad.
===========================================
But does the Constitution actually refer to animals?
I tend to think not. I don't think the Constitution gives dogs, even dogs over 21, the right to vote.
I don't think that bears live much longer than bears. Pandas might have something akin to a thumb, but they are not actually aggressive, and would probably not wish to use firearms.
If one lives on a low-nutrient food like bamboo shoots, one needs to spend most of one's life eating.
I think that the rumors about armed Pandas are the result of misplaced commas.
CORRECT: The Panda eats shoots and leaves.
INCORRECT: The Panda eats, shoots, and leaves.
Plane, take careful note.
