Filou was 15 weeks when we got him. We had known him since he was 8 and with 8 weeks he was an adorable little ball of fluff. With 15 he was more like a skinny teenager -had started to get his long legs and you know, every evening the 2 boys started chasing each other throughout the apartment -behind the books in the shelves, over the window sill. We called it "The Storm of the Mongole Hordes". You could just stand and laugh......
