ONE more pic and I will let the thread die - they seem to be getting along pretty well except at bedtime, which I assume will calm down once they decide on which spots they like. I don't hover up there anymore, but every time I check on them or am in the next room for any length of time, they are quite peaceable.
They're just so dang cute! Thanks again for all of the advice!
