Jackson is doing just fine.  When I arrived Jackson was very friendly from the start.  He was not hesitant about accepting scratchies.  He followed me through the house as I did my chores.  After chores we settled into some serious play.  I introduced him to my cat dancer.  A wire with rolled pieces of cardboard at the ends.  When you shake it, it looks like a bug flying or fluttering along the floor.  He tore around attacking the "bug" and having a great time.
