Oh my, poor precious little Miley! It's times like these that it would be nice to have a video camera playing at home in order to see what goes on when the humans are away. I am afraid that things must have really gotten out of hand this time. Coming home to that must have certainly shaken you up too!!! Thank goodness there were no signs of injury or any bleeding. My two can really toss the fur when they get doing their rolypoly antics but this sounds a little scary to me, certainly not even rough play, but probably an outright cat fight. Maybe you might just want to call Ti's breeder and let them know what has been going on just in case, worst case scenario, that things get even worse with the arrival of Juni. One really needs to have the wisdom of Solomon to handle feuding felines. I am afraid I am totally lacking in experience in that area, but do wish you well with whatever path you have to take. I know you are feeling so torn right now.
