Where is my five star treatment?

The cats at our home live pretty well, in fact, I think they get five star treatment so how come Koko was found licking the condensation off the window on a cold and wintery morning:-





Koko gets fresh, lukewarm water every day so why did she think the service was not good enough or was she trying to give us lessons in the window cleaning department?

Considering the windows are ceiling to floor the window cleaning could take quite some time.
