You know it's a bad sign when...

I was lying on the couch with my cat at the other end. Dead asleep...twitching slightly. The cat, not me. I stretched my leg out, pushing my foot closer to the cat. She bolts from a dead sleep, straight up, hair on end.

I'd say that scaring domestic animals with your feet is an excellent measuring stick to determine if you need a pedicure.

Or odor eaters, but we won't go there.
