I enjoy archery but have never gone bow hunting. Can someone who’s familiar with it let us know just how “humane” it was to kill the cat that way? It seems to me the cat might have taken some time to die, which is a pretty sick thing to do, even if you really think you should eliminate feral cats. (FWIW, we do have former ferals on our property. We trapped, neutered and released them back in place, here on our place in the country. They’ve all figured out where the food comes from and become very friendly. I like having them here because they have FINALLY gotten rid of most of the gophers here, which were endemic!)
You will be blessed for your efforts.
