It's not always easy to understand the cat. Recently, she has taken to sleeping on my bed most of the day, rarely coming into the living room if not to eat. I've missed her company.
Yesterday I cleared the clutter off the top of her cardboard box in the living room, and showed her by putting her there - she stayed for a nap. And has returned several times. Yay, finally we are spending more time together! All I needed was to give her an appropriate surface to lie on.
