I was dealing with a crying, yowling kitty this morning.  Daddy had
taken Boone for a walk and apparently not having anyone to pick on upset
Oliver!  :-)  I had just come out of the bathroom and suddenly Oliver
stopped his crying and looked at something slightly above his head. I
couldn't see anything but he was fascinated.  I had a fanciful thought
that a faerie had come to bring us some good luck.  Oliver then got on
his back legs and started pirouetting through the bedroom with his paws
above his head. He kept bringing his paws together and for a minute I
thought he was clapping to the beat of some other worldly music.  I
still couldn't see anything.  He suddenly snapped his jaws together like
he caught whatever he was dancing with.  Then he actually made a
spitting sound like whatever he had caught had tasted bad and he made
all sorts of comical faces.  Faeries must taste bad!

About 15 minutes later he became fascinated with something else on the
other side of the room.  Steve was home this time and we both looked but
couldn't find a gnat or tiny spider on a silk.  We had never seen Oliver
dance on his hind legs like that before.  Steve suggested maybe Oliver
was hallucinating.  :-)
