Dog Week: Terror Tuesday: A Neighborhood's Revenge

It was a Tuesday, very hot for June,
When Zoe told the others what she'd learned.
The dogs declared this very afternoon
Was when they'd act upon the rage which burned
In each of them. By ones and twos they left
Their yards (their masters working or at naps)
And all, the mighty dogs whose heft
Defeated humans; smaller ones whose yaps
Pierced space and time, did gather at the place
Described by Zoe, and began their Howl
Of Condemnation. Ev'ry canine face
Was black with concentration. One last yowl
And lo, the ritual was quite complete,
Cat killer's screams of horror sounding sweet.
