I called the pet shop I go to today to see what I could do for Ryuichi. They said that Dri-Tail usually works. So I got the dri-tail. I was force feeding him dri-tail and water all afternoon. At first he would fight me and bite the dropper, but around 2:30 he refused to move.
He's hardly breathing and won't move when I pet him. He's hardly breathing. I put some tissue over him to keep him warm and I said my goodbye. I know it won't be long until he goes.
Thanks to all the people who helped and said kind words. I really appreciate it.
Edit: Ryuichi has gone to the big wheel in the sky.
