The two boys are doing well, although Leo had conjunctivitis in one eye we had to clear up. But even that is doing much better after the application of some eye ointment for a while. And no one else caught it, thank goodness.
The introductions are going about as well as we can expect given Treelo's known bad attitude towards interlopers in her space! The boys are spending days out and about in the house now, and only getting closed in their room at night. So far, so good. No bloodshed, yet.
