A RAT'S LIFE

Going underground where the sewers are 
There are much better places by far
The smell is rancid and gets on my nose 
Just part of being a rat I guess and suppose 

I live on the food that you throw away 
All kinds of scraps at anytime of the day 
Considered vermin by those in the know
I don't hang about and certainly not slow

To be a perfect pet is my one ambition 
My one true goal and ultimate mission 
So if you see me around don't set an alarm 
I cause you no ill and definitely no harm
