Sense Sonnet - Pumper

Is this Dump for Real?

The latest news the rhinos get,
Visiting the common latrine.
Male rhinos have their noses set
On scoring gals on the poop scene.
Ready to mate females do poop
Chemical signals that relay
Availability - the scoop
That send the guys sniffing their way.
Nosy humans tested this out,
Doing a chemical do do,
Planting the faux feces about,
Observing the guys sniffing through.

A trick by humans to deceive
The rhino guy to make believe.
