They are good friends. My other cat is not so keen, she takes great pleasure in batting him! They have this weird sat/sun morn thing where they roll on the floor together.
Just clipped Winnie too. He was getting ridiculuously hairy again, much to the disgust of my OH. That's the cats bed, from Ikea, Winston got into the habit of taking it out in the garden to annoy them , in the snow!
