"For Want of a Cat" (Entry 241)

The flea bit on the rat within the grime,
Many existed after the Burning Times.

Executed witches and their familiars, just pets.
The cats were killed, which now they regret.

So out into the world, the rodent ran
from flea to rat to ravaged man.

And on and on and on.

The Black Death scampered,
humanity's growth almost hampered.

And on and on and on.

Death became them, almost all,
this could have been civilisations fall.

For it all started with a flea on rat.
So on they cried, for want of a cat.
