My little boy has been found!  I am so happy!!  Thank you for all the purrs!

My sister-in-law and her family were here visiting for the weekend and
picking up some furniture that we were giving them.  My husband and
brother-in-law had moved our buffet so they could move out a large sofa.
Oliver must have been exploring behind the buffet and when the boys
moved it back they trapped him under it.  There is a very small spot
under there that we had no idea existed.  Steve and our dog Boone had
gone out to see if they could find him one more time and I was sitting
in the dining room when I thought I heard his faint cries.  I looked
every where and just couldn't tell if the cries were real or I was
imagining them.  After I heard them again I finally decided he had been
trapped in the wall some how.  I was just thinking about getting a
hammer and doing some dry wall removal when I heard him meow very
plaintively (I swear that it sounded like Ooouuttt)and I saw the tip of
one paw wave at me.  The space under there is so small he couldn't stand
up and was trapped flat.  He was under there for 7 hours.

My husband and brother-in-law feel both elated and awful at the same
time.  Oliver seems no worse for wear and Meowmie needs a drink!

Thanks again for all the purrs.  They worked!
