Creeping Cat

This is a neighbour's Maine Coon cat creeping through our undergrowth. He seems to think he owns our garden and is not very happy about us plonking a summer house on what he considers to be his patio. I even dared to sit there this morning so he had to creep surreptitiously past me hoping that I wouldn't spot him. He will come into the house but won't let us touch him at all. We definitely seem to be an intrusion...
