The vet visit isn't for another 3+ hours, and I'll post when we get back.
Note to self: do not look up kitty symptoms on the internets as you'll only end up scaring yourself. Eek. I don't know if I want the vet visit to hurry up and get here so that I'll be reassured, or if I want to avoid it because of what the diagnosis might be. Oh please, please let it be something simple and curable and easy.
I don't know if it's because he's not feeling well or what, but Malcolm has taken to dry-nursing. Apparently that's what he wants when he meows at me-- to suck on my finger. He lay in my lap, purring contentedly, and sucked on my finger for a good long while. (There's no clock in my bathroom, but I'd have to guess it was about a half hour.) Zoe would occasionally come by to see what the fuss was, but she seemed to be clearer about anatomy. She was still happy to be petted, though.
Two weeks ago they stayed away from me, hiding and hissing. Now they curl up in my lap and purr. :)
