Black cat Midnight got lost in a storm drain but used her incredible homing instinct to negotiate the maze of underground tunnels.
Owner Jeanette Young, 39, had given up hope of find her when a neighbour heard faint meows from a manhole cover outside her home.
She called water company Severn Trent which dispatched two workmen to rescue the bedraggled moggie - who was filthy but unhurt.
The workmen said the nearest place that Midnight could have entered the sewer system was two miles away.
Miss Young said:
'We are all delighted she is home. She is doing very well, although she was a bit smelly when she first came out.’.
