Mine would keep sleeping forever as long as no one is playing with her. She's very much willing to stay up for hours on end if we humans or cat give her a reason to. No matter how cute and peaceful I think it is watching her sleep, I feel real guilty for being a terrible mommy on those days when I know she's gotten more hours of sleep than play/attention. Her show of consideration towards us motivates me to be more considerate of her. She's been like this before she was 1 and now at a month over 1 years old, she's still just as accommodating.
