I don't think I can express it any better than those who have already spoken but still wanted to say so anyway. So...so sorry. As China said, the fact that he continued to do what he loved is wonderful! He, like my Lucky, went on his own terms.
I've had Heaven explained to me this way: It's interwoven with us and our world, but at the same time like a one-way mirror. So, he can see you and is close to you, even if you can't see him. Just know that he is close and loves you!
Blessings to you and your special Pepsi.
