i can tell that you have a very close bond with Freyja, and it's heartwarming to hear how well you understand her needs.
My own cat, Colita, has a similar way of communicating with me through his eyes. When he wants to play, his eyes become wide and playful. When he's hungry, he gives me a pitiful look with big, round eyes. And when he's feeling scared or insecure, he seeks out my attention and stares at me with a look of concern.
