Yeah, I can understand that. I'm really pleased when my cat catches mice but not so pleased when instead of being hungry she decides to play with it... then I interfere, she gets confused, and the mouse gets free and what's the point in her catching them? We still have a free-roaming mouse in our house. Sometimes it's necessary to have a dead mouse and sometimes they just get knocked around, though that really isn't part of the analogy I think.
