What can you tell me about Catahoulas?

Lo and behold, Kaki is a Catahoula mix. Her last owners told me she was an aussie mix and my guess is that they got her from a shelter. She's definitely not aussie. I lurve her so much that I'd like to get another catahoula but she is a mix so I don't know if her temperment is the mutt or not. I want to know more about the catahoula disposition and all that jazz. Please.
