I came home to find a dying cockroach on my kitchen floor.
That discovery alone is not all that disturbing. I do live in FL, after all, where palmetto bugs are a fact of life and can be found just about anywhere for no good reason at all. No, I quite expect to very occasionally stumble across one in my home, so that was not of much concern to me.

What did concern me was that this cockroach was on its back mostly dead, missing at least two legs on the same side. This raises two questions:
1. If this cockroach came into my house that way, how did it manage to get that far before losing it?
2. If this cockroach came into my house fully intact, how did it end up that way?

I suspect that I would rather not know the answer to the latter question.
