Which big cat is known for its distinctive roar that can be heard from miles away?

It's actually my cat. He's a real big mouth.

Gizmojo, My aunt lived in a block of flats not far from a local zoo. On summer nights, with the windows open, she heard lions and elephants , and tropical birds in the morning. Like Africa !

Gizmojo, Interesting, but scary.

That would be an interesting sound to hear at night!
