Oh, I'm so very sorry to hear about DH.

For everyone else - kitties develop cancers to lots of the sediment used in standard vaccines. Get a kitty-specific vet, and make sure they use a kitty specific vaccine, keeping all these issues in mind.

I don't know what you feed, but would definitely go to a holistic food. We thought our kitty had advanced kidney disease, and our vet now thinks (but isn't sure) after 2k of testing that it's cancer (but doesn't know where). I think putting him on a holistic food has done a world of good - he feels better and has gained back some of the weight he lost.

Please keep us posted.
