I’m officially frozen stiff. I wanted to let Henry out but as soon as I opened the bedroom door to the garden, Johnny the neighbour’s tomcat appeared. He is an elderly gent, about twice the size of Henry. The approach lasted for about 20 minutes (I was dressed for indoors) with Johnny moving one step per minute into our house. He was very vocal, in a deep throated voice telling Henry what was, I think, his claim to the area. Henry first stood with his back arched but then tried to disappear as a black blob in the corner. When I could sit quietly no longer I closed the door and they stared at each through the window pane for a few minutes before both simultaneously decided that enough is enough and left in different directions.
