A big brown??

Yesterday, just as I was pulling out of the garage to head to the Blue Gum Pub with my SCQuilter friends for the day, I spotted this big brown Rat, it was so big I thought it might have been a Bandicoot?  I shuddered then I noticed it's breathing was labored so I drove forward a little thinking... if it's a Rat then good it can die but if it's a Bandicoot should I try to rescue it?  Then I thought... what if its one of those Sydney Rats the Museum is trying to save... it was still moving so I put my window down and saw that it was a piece of bark moving in the gentle breeze!
