Sense Sonnet - Pumper

Poop Patrol

I am a wolf not feeling well,
Pooping diarrhea a lot.
But here at the Zoo - who to tell
About the tummy ache I've got?
Lots of wolves in the Zoo do be,
So lots of poop is all around.
How will keepers know which poop's me?
An I.D.'s needed for my mound.
So what do the smart keepers do?
In my food they put glitter green.
My poop is tested by the Zoo,
And I'm back on the healthy scene.

All that does glitter is not gold -
Can be a way my health be told.
