I got the boys together again this morning. Today I skipped the tub completely and had them on my lap when I opened pouches. They both came out slowly and met in the middle. Sniffing and some moving around, though very slowly; they stayed within a few inches of each other and almost always nose-to-nose. After a few minutes, both on my right leg, Shikoni started grooming Washi. Again, very slowly, almost hesitantly; at one point Shikoni took a toe of Washi's left foot into his mouth and just held it for about ten or fifteen seconds, until Washi pulled it away. Shikoni was marking Washi with his chest gland, and trying really hard to push his head under Washi. Washi was very passive though he did return some of the grooming activity, kind of nibbling and licking Shikoni; and would not allow him to put his head under.
They stayed on me for about twenty minutes, after I stood they moved around, still keeping within a few inches of each other. Then Shikoni jumped down and ran to the door, up the robe belt and peeked out; Washi didn't follow. I think Shikoni was disappointed; he came back and ran off two more times. It was as if he was saying, come on, let's play. Didn't happen. When Shikoni made for his pouch, I got Washi into his also and took them home.
I was curious to see how Kioko would react to Shikoni's scent on his brother. There was really no reaction. Kioko was awake and running around the cage. When I opened the door to put Washi in, he came scurrying immediately, sniffed a couple of times and then wanted his treat. I gave everyone a yoggie. When I went to hang Shikoni's pouch he jumped out onto the floor, and ran under his cage. I closed the room door immediately, finished hanging the pouch and got a mealie. He came right over, of course, and I got him put away.
Right now everyone's tucked away in pouches and barking. I hope they're saying, Hi, neighbor!
