Chuck,
They're doing well, thanks for asking. They don't fight, but Elvis doesn't have much patience with Danny, the "young whippersnapper."
Sometimes Danny runs up all happy, trying to play with him and Elvis just thumps him one on the head. He doesn't scratch him or anything, but I feel bad for poor Danny. Elvis seems to be getting better, though. In the beginning, he didn't want to cuddle with me together with Danny, but he seems to be getting a little better. He's starting to learn to share me. LOL.
The people at the shelter said that two are better than one because they play together and keep each other company. Maybe that will eventually happen, but for now I think "The King" needs some time.
