Mimi and Lulu playing Tai Chi with each other

After the hamsters' big fight, we tried to put either Mimi or Lulu into each other's cage, but they still ended up fighting each other off T_T

So we have this idea to try to put them 'on the ground' aka open air condition and see if they can still be friends outside of the small cage. The video below is the process of encounter, they seem like playing Tai Chi with each other :D

Though the video didn't show, Mimi ran away from Lulu in the end, still afraid of her. The evidence was the 'nervous poop' by Mimi that you can see in the latter half of the video, poor hamster!
