Do you have a dog that thinks it is a cat?

My female Blue Heeler/Australian Cattle Dog thought she was a cat. It didn't matter which kitty's bed it was, it was her favorite bed to lay in. Not sure why she didn't like her bigger dog bed... But this was always how it was. She also preffered the kitty toys: balls, rattlers, mice, even the mouse on a string. She even did her best to steal their food.

Does your dog like to think it is a cat?
