His bird

Joy finally snatched a tweety bird -
A joy that might have been unheard
Of in his teeny, jungle- tainted brain.
Granted, sparrow, having crashed a pane
Was dead. Still, the thrill of a head in mouth
Gratified a cat whose whiskers, at the thought,
Trembled daily during bird watching. Thus,
The white-crowned sparrow served as a plus.
Watched by God who rendered brief the pain
A domestic cat triumphed over winged strain.
