He woke up while ago and it appears to be the same size as the other one. I'm going to check every 30 minutes and one hour throughout the day. As before, I noticed it mainly the past two nights, at night, when he *blinked* several times it was like that one didn't open up as totally open as the other. When it did, it was only just a hair smaller-looking that the other. (Like it wanted to close or stay closed but it didn't stay closed, just didn't open up entirely.) If this is only at night (which I'm really going to monitor after the daytime monitoring) then that's wierd. Could it be that he's sleepy? But, one eye doing it. It's not a twitch either. Of course with their larger eyes, I've read that they're going to have a tad more watering. That eye had only a small amt more than the other.
If I see it occurring again, yes, I'll call the vet in the a.m.
