For Breaking News from Aggie and Wally's Dad:
With Aggie & Wally no longer making themselves scarce (and after a reassuring brushing for the both of them), I took them into the main hall and shut any doors/escape routes and took the risk of bringing Madie (may-dee) Mittens (the Kitten formerly known as HellKitten) downstairs tightly in my grip. Ah, "O [strange] new world / that has such [kitties] in't!"
There was much posturing and slinking from the oldies and stoic stillness from the newbie, but no fur flew and no blood was drawn.
Wally skulked about while Aggie stared suspiciously down at MM, and MM stared suspiciously up at Aggie.
