I agree adding to my last list are the names when they want too. All I have to do is say the name in a normal means loving, in a stern voice and the named knows who is in trouble.
Lucky come- he will come and snuggle on my chest, "LUCKY" now he ducks.
Demetri dose about the same, but when he gets "DEMETRI" he just stops and looks at me like, what, I didn't do anything.
No they WILL NOT answer to anothers name.
It is funny that with 6-8 around at any time, ONLY the one in troublle knows it.
