I have a boy & a girl, so I can't really help you out...but I hope Jessica & Polly will learn to grow on each other & become friends. I got Momo when he was a pup & Mimi was over a year old back then. She played w/him alot & even slept next to him. Just couple of months ago, whenever Momo went over to Mimi & layed down next to her...she would get up & move. I'm almost wondering if it's hormonal. Now...they're playing w/ea other alot again...& she doesn't move when he comes over to her to snuggle.
