C is for Murder

I just read an astounding bit of information. Apparently only 1 in 3 housecats kill. I'm amazed that two out of three housecats are not murderous. Now this study was done in the US and maybe it's flawed, but it suggests that it might be easy to breed cats that don't kill. Putting aside the question of is it ethical to interfere with the perfect killing machine. (It is, just ask Winston Churchill.) If you take the murder out of a cat, can we still call it a cat? I'd say the answer is yes, although it would be easier to do if they were originally called cmurderats.
