New kids on the block

With the season all but over apart from the lingering wonderful weather, folk have left their summer homes, and so the feral feline population is having to look further afield for food.  These siblings started showing up last week and are two of the most stubborn kitties I have had to deal with, and no amount of water spray has deterred them. They are also two of the most affectionate purr monsters as they are very used to people.  I have named the black and white one "Persistence" and her sister, the calico, shall henceforth be known as "Constance" for their sheer tenacity and determination to, if not move in, at least be served dinner.
