Well, anemia can sometimes be treated! I know he has other problems, and I know you don't want to poke and prod him to make his life miserable, but one thing that can help with anemia is simply giving him more Vitamin B. Did they give him a Vit B shot while you were there? I just looked up anemia on Tanya's kidney site (my go to for pretty much anything), and found this product, which she added to a little baby food and her cat gobbled down with no issues http://www.vedco.com/index.php?option=com_content&task=view&id=136&Itemid=26. And it's not very pricey. Did your Vet discuss ANY treatment for it? There are others, or have you decided enough is enough
