I am thrilled to report that Doug is getting along fine with Stanley and Elisa when they are outside of their cages. They can play on playstands together and hang out on me together. I knew Stanley and Elisa would not be a problem, but was worried Doug would bully them. He is still a baby, so perhaps later he will, but for right now they are all fine playing together. Doug LOVES scritches. He will crawl into my hands just like Shira does to demand scritches. He also sits on my fingers and watches the computer screen, like both Roni and Shira. It took him about two days to realize that if he picks at my skin I will put my hands up and he can get onto my hands and demand petting. (I know - behavior that is increasing is being reinforced.) Stanley, in her typical watch and learn fashion, is now doing the same thing. One game Doug enjoys is landing on Stanley's tail for a short ride. As always, everybody loves Stanley.
