The kitten is running wild, bouncing all over the house, and shouting shrill yips of delight when he sees us. Au is curled up in a new box that arrived with a new fan. He's enjoying a quiet morning snooze and groom session.
Au and the kitten, called Mr Snizzles while we think of something more manly and appropriate, are getting along fine.
They started playing race and chase on Saturday, with one cat touching the other lightly (counting coup, American Indian style) and then rushing off at high speed.
Mr Snizzles usually starts it by pouncing on Au, then Au chases the kitten through the living room and garden, there's a turnaround and then the kitten chases Au back into the house.
I think they're enjoying themselves and they'll soon be firm friends.
Here's Snizzles, checking out the camera.
