Minny doesn't have an aggressive bone or cell in her body. Bitsy has come in and taken over...Minny won't even protect her canned food - Bitsy just goes over and runs Minny out. Bitsy had no problem sleeping on the bed - I make a ramp out of pillows and she and Minny were up and down with no problem. They are getting along wonderful - playing very well together. They are playing tug with one of their toys right now.
