Why today? Because he is a C-A-T and it is always in their own time.. Congratulations on his purring.. To me, that is a big step!

Are you trying to get him to play? Sit down with toys and try to entice him to play with it (and you).. Get than interaction thing going between you and him. I think once you get there, you become "friends"..

Wish you could post pictures of your cat in the sack!
