Cera and Ducky are doing just fine - they're on antibiotics, bay/doxy. They were pretty healthy to start with but we don't want to take a chance in case they get an opportunistic infection like Petrie. Right now my sister and mother are taking the very best of care of them - if nothing else, this is showing how much Mom has mellowed, because she was willing to put on a glove and move Ducky a bit in the cage (she was hogging the food). Before she wouldn't have done this for a billion dollars, or if she'd had a metaphorical gun to her head.
I'm not sure I want to write Petrie's memorial until I see her - it seems somehow unreal, still...
