My Cardi likes to hide behind doors or under tables with just enough visibility that he can spy on us. Then when he wants to be fed/scratched/entertained he is all up under our feet. I swear he's part cat!
That's great! Finn just wants to get somewhere dark where he can get left alone. It's hard for him to be the only man in the house sometimes!
So sweet! Your curtain also serves as a cozy blankie :)
