It may be that in cat form it has similar predictive properties, such that the cat moves before the window is actually opened because parts of the cat extend into the near future, motivating movement *before* the window opening starts. One wonders if arresting the opening of the window before completion of the act would then cause the cat in motion to seek other sources of outside air (much like trying to prevent the wetting of pre-dissolved thiotimoline), perhaps causing the cat to pass through the (now-closed) window and thus achieving outside air anyway.
