Question

When can I  use  it?
In  which  situation can  I  use the  expression: "you do not stand a cat's chance". Can someone provide  an example situation , please?

Answer

Ok.

If someone were to ask, "Hey, do think I could jump off the Empire State building and live?"
You could say, "You don't stand a Cat's Chance!"

Answer

I've never heard this expression.  We say that a cat has "nine lives" (or nine chances), so it doesn't make any sense to me.

Answer

I've only seen the slightly longer phrase "a cat in hell's chance" http://idioms.thefreedictionary.com/have+a+cat+in+hell's+chance

I agree with Taylor's example.
