Both "The Royal House of Thebes" and "The Warrior of a Warrior King" have a tragic heroine in common. In the former story, Antigone sacrifices herself to give her brother a burial. In the latter, Queen Boudicca's land is attacked by the Romans. As a result, she decides to commit suicide to avoid being taken by her enemies.
Well it sounds like the "she" in the story is a cat because it says she falls asleep in the sunlight. Cats tend to fall asleep in windows and in the sunlight. Cats also migrate from place to place to find a comfortable to rest. Lastly, it states that she might find a mouse. Cats chase and catch mice, too! Hehe hope this helps you! :)
