Well, Laurie - there aren't enough words to cover all the emotions that I'm feeling for you and Lazio right now. It's hard to balance Joy and Excitement with being Nervous and Unsure, especially about decisions that need to be made.
I wish I had some words of wisdom to share - but, you alone know what is best for Lazio - and thus far you have a good support group around you to give you the pros and cons of what, if anything, to do next.
He might become a poster child for feeding raw food, too. 
(I wish I had the where-with-all to feed all of ours raw. I'm hearing that people are even feeding the FeLV raw with success - amazing!)
Lazio, and all your gang, are blessed to have you caring for them, and as I said before - I'm confident that you'll know - when you need to know - what sort of medical attention Lazio will require.
Maybe just letting him "rest", and giving him good, life-giving food, and loving, is all he needs right now? 
Blessings Laurie,
