Another bug bite that is oftened described as a bulls-eye is the bite from
the Brown recluse spider.  Very nasty thing so I suppose if that was it, the
owner would have freaked immediately.  I had one on my back leg once.  Very
unpleasant and I had trouble sitting for a week or two.  Not to alarm
anyone, but the bites from one of these spiders can be deadly.  Since I got
bit (I was outside) I have become very diligent in removing all spiders from
the ferret room, just in case (or cause I'm paranoid, whatever).  Actually,
I have become very diligent in removing all spiders from my general
vicinity.
