thanks! Right now I think we've settled on the name Luna (it's my husband's favorite Harry Potter character said she reminds him of me).
So far things are going ok. Besides chasing them around like "oh my god is she gonna pee?" There's been a few growls because of Fred's over exuberance for life and rough housing and Luna's quest for relaxing and chewing. But all in all I think they like each other very good and share good.
