Between knowing I had to be up to teach the early class (I'm doing a double) and worrying over Handsome Tom, I slept poorly. At quarter past six I finally gave in and hauled myself out of bed. Bleary-eyed, I shuffled out to the gym and lo! I was greeted by a considerably perkier HT. He meowed at me and immediately got into my lap when I sat down. He's still not eating, though he did nose at his food a bit. Mayhap I'll try the tuna again.
Still not entirely out of the woods, but at least things aren't quite so dire.
