Broom stick it.
You DO NOT want to inhale that "dust"... it is platnium and is very toxic (think of what it has been collecting since day one). Run some water inside the cat before you hit it... and while you are hitting it and into a bucket with about 1" of water to start.
Watch for the boost increase 1-3psi... depending on the style, age and condition of the cat you are gutting. headbang
