While posting the pictures of the kittens "doing yoga" I thought how much the little gray one looks like IHAVECAT's Petie. Similar.. but not exact. So I was spitballing female names for Petie, and ended up with Petra.
That seemed to fit like a glove. So I went to read up on the history of Petra ended up with the following names..
|Ludwig, Petra, Miriam, Musa|
