It's only been 10 days

Yes, the newbies have been making furtive forays into the rest of the house.
No, no pix yet because they are still 99% hiding in the far depths of the library.
Some signs:
Mya was caught in the kitchen yesterday evening by Sienne, who is not yet ready to share.
Mya was also spotted by JP fleeing the living room when we got home last night.
Someone made the floorboards creak on several occasions during the night, and it wasn't Sienne because she had been tossed outside to give us all a break.
The litterbox in the kitchen is far more popular than the one in the library. It is filled with clumping cat litter, while the other has plain litter. The trek to enemy territory is apparently worth it.
Dyson (sorry, but I just can't have a cat named for a woman-beating criminal. I think the cat will get over the switch to a D from a T. Otherwise his name would be Number Twenty-Seven.) allows himself to be petted from the depths of the cloth armoire where he usually hides.
