Weird Wednesday: Small Victories

They'd come from space; to space they would return,
This mighty warlike fleet -- but lo, a cat
Had swallowed ev'ry ship! They'd have to burn
Their way out of its flesh. Each spaceship that
Now found itself within began to fire
Its lasers. Meanwhile, on a mat, asleep,
The puss began to glow. Its state was dire,
But mercifully it did not wake ere, deep
Within it, came destruction. Now all, free
And angry, did the ships emerge to blast
To rubble ev'ry city they found. We
Cared not to lose our termites and, at last,
Our ants, but slowly all here came to ruin
As none did what those bugs had e'er been doing.
