I'm going to tell you that getting another one was never an option for me. Mimi was perfectly content with her dog sisters and hated other cats. She still does, therefore she and Butter are bitter enemies. He just wants to play and she bristles at him every time she sees him. I justified keeping him when he showed up because I knew no one else would have him, mean thing that he is.

My humble opinion is that if Ally is content and you know you will be moving eventually, perhaps it would be better to wait until you get settled into your home, then consider it again. But I completely understand that urge for just one more! That's what happened to me with the dogs!!!
