Oh how awful! I am so sorry for your loss.....
I live in Monterey - I can't take Buddy but I could help with transportation. If you can't find someone to take him, don't forget about the wonderful cat sanctuary near Fresno - Cat House on the Kings. And there are several no-kill shelters in the LA area.
PM me if you want.
I should also add, my husband died very unexpectedly so I can relate to what you are going through......hang in there, hon......
