hiding places for cats

I currently do not have a cat, but when I did she found so many different hiding places; it was usually pretty hard to find her.
Her favorite place to hide was in the closet under all of the blankets.
When she wasn't there we could usually find her under one of the beds, behind the couch, in a basket or sunbathing in the windowsill. There was a few times when we wanted to leave for vacation and she was hiding in the closet and we looked and could not find her. She always did a good job at blending in with all of the blankets.
