From A Wiki of Ice and Fire
Pantera is a six-breasted cat goddess worshiped in Lys.
When Larra Rogare worshiped the various gods of Lys while living in the Red Keep, she was joined by her ladies, servants, and guards. Because cats were often seen coming and going from her chambers, it was rumored that they were her spies. Some stories claimed Larra could even transform into a cat so she could prowl the gutters and rooftops of King's Landing.
Matteno Orthys, a magister of Lys, was a fervent worshiper of Pantera. His prized shadowcat mauled and partly devoured him when its cage was left open one night.
