I'm often seen around a lot, referred to many ways,
See me black and you may find misfortune haunts your days.
Tell a thing, that should have been kept quiet, to all around,
Then look inside the sack, there I'm no longer to be found.
Nosiness, prying, snooping, leaves me fearing, full of dread,
For all these things are likely to see me soon lying dead.
These clues combined should start to give a picture, an idea,
Of who or what I am, so can you tell me? Is it clear?

Answer

If you thought those clues lead to a cat then happily you're right,
For bad luck is yours when a black cat should come across your sight.
And when you reveal a secret, even though you said you wouldn't,
You've let the cat out of the bag by telling what you shouldn't.
Nosiness, prying, snooping and inquisitiveness, oh drat!
They make up curiosity, which, we all know, killed the cat!
