Aaawww I see. Pretty ladies ! Cats are not fond of changes but they are in good hands. I guess the boys were inside while the girls were outside ? I could imagine it would be too much stress to meet the gang.
These are my brother's two 12 year old girls, Squirrley on the left, and Mischeif. I am babysitting them while my brother moves from Upstate NY and gets a place here. They are pretty stressed, as they have been outdoor cats all their lives, so the sudden change to an enclosed area with no woods isn't good right now.
