With my cat “Shadow” by name the possibilities are endless, including but not confined to: Watching birds out the window, playing with his toys, making mad passionate love to our feather duster, (made even stranger as he was “fixed”, early on,) and getting his claws caught halfway up the wall heater and hanging on for dear life until he is rescued.
Heaven and Hell are such great concepts to play with, unfortunately mankind has the bad habit of treating them like actual places.
