I would like to formally announce that we have christened our new little addition Betty Blue. After looking around on the net, it's pretty apparent that this little girl is a Russian Blue mix. She has white paws and a white bib, but she is clearly blue/grey and has a very Russian Blue face.

Boo is easing up and Betty is getting out from the sofa and actually exploring despite Boo's occasional growl.

Any words of advice on how to make Betty feel more secure??
