They know

Have you seen a bird stop mid-song
And fly away without a sound?
Have you seen a cat stop purring or playing
And quickly run away at nothing?
Have you seen a dog pause
And growl
Shrinking from empty air?

They say animals know.
They just know.
And you better listen to them
Because when a bird stops singing
When a cat is staring
When a dog starts growling
You need to stop.
Just stop.

Because the birds can see
Because the cats can hear
Because the dogs can smell
When there is something
Terribly
Horribly
Obviously
Wrong.
