Scared no longer, one month in, the kitten is fully in charge. Slightly subdued after neutering last week, in the last few days she has made it clear she is Fully Better And Ready To Play.
At midnight. For hours. Agh. I was scared to look at what she was killing under my bed last night - from the noise I was fully expecting perhaps a buffalo or a wolverine. It turned out one of my slippers was evil and must be punished 
So, for the sake of my sanity and my sleep, what are your best games and toys for attempting to exhaust a seven month old fluff ball? We play regularly through the day, I'm home with her all the time. I've just done an extra half hour of chucking her favourite toy around the place for her to retrieve. What else can I use / delude myself that might work?!
