For the last 2 years we have had a ginger tom cat visiting our garden. He was alway quite timid but, over the summer, he became bolder and I worked on gaining his trust to be able to catch him and have him neutered with the intention he would be released into our garden (which borders a park and is 100m from the nearest road).
He seems to want to be friendly, and will headbut and purr, but then attacks my ankles or hands without provocation. He sits by the front door and it's getting more and more difficult to get in or to feed him without being attacked. Does anyone have any ideas about how to calm him down?
I have 4 cats already and they are frightened of him, so bringing him into the house is not an option. He's currently locked in the garage because of the weather.
