Pet Port A Potty

I took a walk in the city today
to try to pass the time away.
Saw lots of people walking too
stepped right in a pile of doggy doo.
I thought for a moment just what could be done
to clean up the streets of doggie dung.
Maybe I'll invent something really super
even finer than a pooper scooper.
A port a potty for our four legged friends
on every street corner where every road bends.
Then I'll become famous for this awesome invention
at the monthly town meetings my name will be mentioned.
They'll throw a big party and dance in the streets
because never again will there be poop on our feet!
