"Cats are crepuscular and not nocturnal like most people believe. This means that their activity levels peak during the twilight hours of dawn and dusk. Between these times, they may be storing energy for what they perceive as their next ‘hunt'. And, interestingly, cats actually don't sleep as much as we think. When we are out, they may be wandering about, looking out of the window or in the garden. Some cats simply sleep long periods due to lack of stimulation or boredom."
