There are many reasons why everyone calls her Kitty....... given that her name is actually Rose.
Mostly because she is very feline by nature, she moves in a slinky Graceful way, She loves curling up on a nice soft sofa, she hates the rain, She hates the cold, she has a tendency to jump 3 feet in the air when startled and she loves having her belly tickled and has been known to purr a lot. :)
