Let There Be Stripes!
This did turn out to be a nice, quiet weekend and Max seems to be feeling completely normal again. He's not growling at anyone anymore and is playing and attacking and cuddling and purring just like he was a couple weeks ago before all this eye stuff started. Also, we don't have to put drops in his eyes anymore. That's huge, as anyone who's had to put drops in a cat's eyes can tell you.
