Evening exercise

In between trying to befriend Jaffa, Guinness engages in long, noisy chases with Gizzmo. Currently they are flying up and down the new cat tower... 

I wish I had this kind of energy for exercise. All these days off are tiring when you're on compulsory unpaid holidays thanks to other people's religious holidays and an end to yet another calendar year, can I go back to work soon please...?
