Since Marbles keeps getting locked in the bathroom, you may want to put something in front of the door to help prevent it from being able to open up so easily. Both of my girls will still growl and hiss at Alani & Blaze if they try to bug them too much. I keep telling them that they just want to play with them. I've found that females can be such drama queens. I hope that Flo-Jo,or whatever her name ends up being, will start to settle down soon. Good luck.
