Whenever one of Hollowfox's cats catches a mouse, the cat is given soft food as a reward for bringing the live rodent to her humans. Then the mouse is realeased, outside, with a stern warning.
My late lamented Ocelittle (as opposed to ocelot) used to bring live cicadas inside and turn them loose. Hours of fun for the whole family.
Then there was Soloman who liked to bring us half a dead squirrel every now and then, always the bottom half.
Just in case you're wondering why Viggo and Gracie don't go out.
