The secret with Kooky appears to lie in the catnip drops. Shaking the tube, I was able to lure him onto the bed and groom him for a bit. I also managed to get him upstairs several times using this method. Julian came around later and played with him for quite a while.
Had lunch at Lye Torng today and Ray very kindly popped to the shopping centre to buy an Observer for me. I felt really spoiled, it was so kind of him.
