Dear Catkin,

I am very glad you can operate your legs now, unlike when we brought you home and you were completely splayed and could hardly walk, let alone run or even think about jumping. However, it is not necessary to jump on top of everything. Candle sticks are not cat toys, and items on 6' high shelves are there to be out of the way, not to be seen as a challenge for you to overcome.

And please just forget about sneaking out to climb Whitney, Kilamanjaro, or Everest--by the time you got there you would be old enough not to care anymore.
