Paths More Travelled

I have a question for the tiger, padding
endlessly around a path she has worn away
through three years of exploration.
She always keeps her home on her left,
and on the right a giant metal fence
that she has only once made contact with.
Why would you when it doesn't bend
with the wind, or run away in fear?
This same animal burnt bright for Blake.
If I could I would ask the tiger, what
would she do if the cage disappeared?
Would she stick to the path she knew,
or would she take the chance in a new world?
