Ali knows when I'm not feeling well. She's not one to normally come and snuggle w/ you, but she does when I'm sick.

Jack always is snuggling w/ us, so it's no surprise he's right there when I'm sick too. But he doesn't like it when/if I cry. He comes up and nips at my arm or leg to tell me to stop.

I think cats in general don't like it when people yell. I remember when I was little my RB cat Twinkle came up to me and literally stuck his face in my mouth when I was yelling, as if to say "put a sock in it!"
