Amberlee, They never interact at all. It's sometimes very frustrating to me, when I know that they're bored. They never sleep close to each other either. Each one has a totally different personality.
Schatzie is a Loner and somewhat skittish.
Phoenix is cranky and moody. He doesn't like to be touched and whines when you pet him. The only Time he is nice is when he wants something.
Auggie is a perfect little Angel, so sweet. The other two used to beat her up, but she stud her Ground.
