I am as big as human feet

My mouth is a brutal-killer

I will bite humans if I have to

And every day my meal could be a red squirrel.

I can dash up trees like a Cheetah

I sometimes sleep in trees 

And my fur is as grey as a grandads hair

I am a fast-runner as is sprint across the woods

Watching waiting low on the floor as day goes by

My eyes dart like commits from the sky.
