The Last Earthlings

Many of Earth’s species had traveled with humankind across the stars. So many beasts have reached so far:

Trillions of cows mosey across a slaughterhouse continent on AH-23.
Hundreds of worlds’ alleys are stalked by cats.
Pigeons: pigeons everywhere on Sinclair 8.
Packs of feral dogs haunt the purple boughs of Gerys,
the King’s Planet.
They say there are two pigs
for every gutter,
in every city,
on every asteroid
in Galaxy V.

Chickens, rats, mice, and diseases upon diseases wreaked havoc on species after species, planet after planet falling to great conquering waves of cold viruses and poultry. Most of them were now gone forever, doomed to bumble about as senseless phantoms in the Underworld.
