Kai was really keen to help me clean the mouse house tonight. He normally declines holding them but tonight he said yes. He was totally delighted holding Ruby and giggled the whole time because it was tickly. Then Luk honed in for a turn. Then Jia came and tried to take over and reclaim her mouse. Uh no. She hasn't participated in a year! Now that Kai isn't afraid we all need to watch out for him opening the cage.
