Keeping my fingers crossed that it was some sort
of false positive in the previous test.  According
to a very general screen, my two boys should be
dead from kidney failure (*grins at Clive, who is
currently lying on her feet and snoring*), but
more advanced tests show that for some reason they
just have an abnormally high level of whatever
chemical trips that first screen.

Here's hoping you'll soon have a similar story to
tell.  :)  And a cat back on your feet.  :)
