Vidya Balan has always tried to be pretty different from regular Bollywood actresses.

And now we learn that she has an unusual fear, something which sends shivers down her spine. Interestingly she's paranoid of cats.

A source from one of her units says, "If there is a cat on the sets, Vidya drives the whole unit crazy. She sees to it that it is chased out. Until then, she remains petrified."

But she doesn't forget to display her humanitarian side as well.

The source adds, "Though the actress is scared of all cats big and small, it saddens her if someone hurls stones at them. She can't bear to see that. She just tells us to shoo it away."

Looks like this one is hell bent on being an unusual babe.
