Kim,
While I don't necessarily feel someone like you needs another angel looking down on you and your kitties, you have another one now, Pee Wee. Life is just not fair. We lose the ones we love always before their time. You are a Godsend. A true Godsend. Keep the faith, and know that you made the true and loving decision in helping Pee Wee make it to the other side.
Hugs to you and your girls, and the other kitties.
Johanna
