Still not up to a proper post or catching up on replies/email, but I wanted to blurt this out before I forgot:

Yesterday or the day before, I looked at Perrine and her pupils were missing. Not just thin slits -- I couldn't see them at all. I'm not certain exactly what was going on there, because usually even in full sunlight I can see a slit, and this was daytime but indoors. (Ten minutes later: normal-looking cat eyes again. And she acted like she could see just fine. So I'm assuming this is a normal phenomenon I'd just never noticed before, rather than a malfunction.)

She could see (AFAICT), so her pupils had to have been letting in some light; they were just too small for me to see them at arm length. Don't you start getting diffraction effects interfering with resolution at really high-numbered f-stops like that?
