Finally yesterday, at the osteopath, Tanaka came close to Akira's carrier and gently hopped in. I was flabbergasted! Adrian was surprised. But we both acted as though nothing had happened and Adrian continued with both their treatments while talking to me quietly.
Tanaka and Akira both in the same carrier and Akira actually made space for him. Neither was yelling or scratching.
Tanaka put his head on Akira's back and she allowed him to do it!
Adrian, their osteopath continued to give them both the same treatment and they both relaxed.
Tanaka when he first came 10 years ago.
For as long as I can remember these two can't get along for many years. Tanaka thinks Akira is a cry-baby and Akira thinks Tanaka is a pest. In the last 2 years, after many tries and experiments with Fern's help, Tanaka was much more relaxed around Akira and she with him. Of course there were some spats but not serious ones. Then yesterday it happened when I was least expecting it.
I managed to get them both in the same carrier on the way home but a quarter way in the journey home, Tanaka decided he wanted to see the view and so he hopped out of the carrier to do just that. However, this did not continue at home and they were not suddenly cuddly :) So we will try to see if they would eat closer together and sit closer together as well, if not next to each other. We will see if Tanaka will get into the same carrier next month as well when they both go to see Adrian.
