i have this hilarious headcanon of her seeing this guy at the grocery store and being like why does this man look so familiar? only to find out that she's intuiting it's the goddamn cat. idk what you have for him just yet, but i was imagining he's just a stray keeps coming back, so she lets him in/feeds him/keeps him a couple days at a time. when he scratches to go out she lets him go. it would give you room to have this whole other human life out there, which is kind of psychopathic. she'd be as impressed as she was infuriated.
