No way a gun like that can
not blow the mouse to smitherines.
My cat is getting older. I think he is about 12 now. When he was in his prime he would stay out for 24 hours or more without seeing him. He would bring home big rabbits mostly, and ground squirrels and the occasional rat. Well, there would be guts on the doormat oftentimes. He would not wait to show us.
Now we have resorted to simple poison, since he stays in and sleeps most of the time.
