Thanks for the small flood of responses from you FMLers.
 
This morning Rocky was still pretty runny, but by the time I got home and
woke him up, there was a firm, large, less runny surprise for me in the
corner.  Thanks to Anthony, who mentioned vomiting as a symptom - Rocky
hadn't resorted to expelling stuff that way - a huge relief when I read
about it.
 
Thanks for your help and advice!
 
Justin.
 
P.S.  I got the videocam out tonight, and I'll digitize a few pics of Rocky
tomorrow, and get them up on my yet-to-be-released new web page.
