LOL. Cute story. My cat, Hank, did the opposite. He brought me a mouse from OUTSIDE... his idea of a gift I guess.

He ran in through the open kitchen door with it in his mouth (it was still alive) and when I screamed, he dropped it and ran back outside and the mouse ran under the cupboard. Fortunately, my neighbour and I managed to get it in a shoebox and release it outside. The little guy didn't seem to be hurt. Hank doesn't seem to want to kill mice; he just wants to catch them and bat them around a bit.
The cat I had when I was a kid, Pussywillow, one day brought my mother a half-dead seagull. He dropped it at her feet on the patio. He seemed very proud of himself. Mum was not quite so pleased.
