We originally got Luna because she was such a cute and promising rat deterrent. When she was still a kitten she would hesitantly chase rats her same size around our yard. She's all grown up now and there are no rats.
But there are birds. Yesterday morning at 6:00 AM she brought a gold finch into our bedroom and let it go so that it could half fly around our room for her to chase. When I finally got a hold of the bird Luna jumped 3 feet in the air and grabbed it back out of my hand. This morning, I came home from running errands and found a huge dove dissected on our bedroom floor. I have to admit she's pretty good at hunting. I feel a little bit of pride mixed with disgust - probably how a parent feels when their child wins an MMA fight:
