Oooh, I should have done my own Springer update. After posting here yesterday, I called BTD's parents and did a house visit. The cat... after all I'd heard about how he was acting two days ago.... COULDN'T HAVE LOOKED BETTER. Honestly.
Cats can be so sneaky about disguising how they really are feeling. Knowing what I know about the situation, I'm still concerned - but he seemed to be on the up and up.
Keep your fingers crossed, prayers, vibes, well-wishes and good voodoo to your own liking are much needed and I'm sure will continue to be gladly accepted.
