Who do you think you are?

I am the owner of the courtyard in which these and several other cats sit to bask in the sun, shelter under the wall, chase birds and whatever else cats like to do. Feral cats are a bit of a problem in the village. Last year we had a nest in our garden. At least one of this trio belongs to someone but all the cats seem to believe that the courtyard is theirs and are quite put out that I think otherwise!
