Animal Voices

My cat is very subtle, so I named her Innuendo.
Not so for the dogs, who always speak in a crescendo.

When they feel romantic, cats may wail an eerie tune,
but dogs need no testosterone to prompt their nightly croon.

Cats vocalize for grand events. Dogs blather on at small things:
a squirrel on the garden wall–literally all things.

Every passing siren causes canine howls to bloom.
They seem to herald catastrophe–to signal the world’s doom.

If cats should chance to dream a tune, they keep it in their bosom,
but I think dogs release their songs simply to amuse ’em.

Word prompts today are: innuendo, bloom, bosom, blather and tune.
