Jashoffa,
I have a DD and a brit. My DD was introducedto our adultcat when he was a pup. In fact the cat still beats up on my DD and Brit when they are sleeping at times. As my DD has grown his prey drive has increased dramaticlly. I will not allow the two to be together alone. If the cat gets outside and runs from the dog the cat is quickly mauled by my DD but I am right there to call him off. This is the last cat we will own. It is too much work to keep an eye on the two of them all the time. Eventhough you want to please your girl(same reason my wife got her cat) I would highly reccomend against it. The lastthing you want come home to isyour fianc'e crying over the dead cat your good ol'e hunting partner thought was game for himto dispatch for you.
The Best of luck
