I'm very proud of Luna. There was minimal hissing, and she initiated a lot of the play. Sol doesn't quite understand why Luna does not want to be her friend, but we're well on our way to having 2 very happy sisters.
Here's how silly the doorway looked. Luna could still crawl over it, so we are sure we're there when the door is open.
Crouching kitty, hidden ...
and the play begins!
They touched and did not exchange hisses!
We're starting to really get them together more so we can soon move to letting Sol run free in our house. The vet wants us to contain her for a while longer yet because of "potty" issues. She's so little, so she could get stranded on one end of the house and forget how to get to her litter box.
