We don't know if this works yet.  I only know that I'm allergic to it.  I
can live with that if it works.  The cats were none too pleased with
smelling like lemon verbena or whatever the main ingredient is, but they've
become accustomed to it, more or less.  I can tell you that the house stank
so good for a while, though.
