Moon - the picture I am using is of Charlie being extremely interested in 3 white roosters who kept coming over to our property from a neighbor. They ate our bird seed, pooped on my brick paths, and were general (although not intended) nuisances. At first I thought they were cute - that wore off pretty quickly. Eventually I complained diplomatically and the neighbor took steps. I was sorry, but their fate was preordained anyway - he just moved it up a bit. Charlie found them endlessly fascinating - he barked (they ignored), jumped up and down (they ignored), and generally got plenty of exercise and entertainment.
