Sure, those big kitties know Bramble is a little kitty. They just don't know what to make of her, thats all. Unlike doggies, most cats are not confrontational...they don't have that same sort of territorial drive. So, when given the choice to fight or flee, they will prolly flee. I imagine within a week or two, the bigs won't be scared of the little. Then you have a whole nother set of questions to ask us...he he he..
