I had a stray adoptee; wonderful fellow named 'Boyo,' with the sweetest disposition - love personified. I was ill and lying on the couch one night with a high fever and chills merry-go-round, and he came from across the room and stretched out on me to 'keep me warm.'
Turned out to be pyelonephritis, a severe kidney infection, and I was in the hospital for five days.
Apparently he went looking for me, and never returned.
