I've got a cat that hunts spiderwebs... Every morning, she wanders around the house sniffing them out, and eating them. I wonder how they really taste, besides slightly sticky?

Since the entomologist's other main methodology for finding termintes is to tap all over your house with the butt end of a screw driver, and poking your house with the flat end of the screw driver when it sounds "soft" inside. I'll take the dog route to lead the guy with the screw driver where to poke...
