[Game of Thrones] The Lannister's are represented by a lion. Where are the lions in the world?

Are they anywhere near Casterly Rock? The other houses animals' live in close proximity to those areas.

There are definitely lions in the Westerlands. House Clegane's founder was a Lannister houndmaster who was ennobled for saving his lord from a lion attack, losing three dogs in the process, hence their sigil.
