When the Missus and I took in the stray kitten we named Mili she instantly made herself at home. One day, when it was cold, one of us laid down on the couch and covered ourself with a blanket. Upon getting up the blanket was folded and placed on top of the couch back. Mili decided that this was to be her bed, despite the one we purchased for her.
She makes herself so comfortable and is so relaxed on it, we just leave it there for her, save for regular washing.
