I'm so sorry you are going through this. I wish I had more words but I don't other than to say just love your baby and when and if it's time you will know.
I too did the vet hopping thing with a chronically ill kitty, I know there are some very poor vets out there. I did finally find a very good clinic which is also cats only. It's unfortunate that it's like that but that is the way it is at least where I live.
I'm so glad that he is doing better! Please don't rule out all vets though. I have had horrible experiences with them as well....more times than I'd care to count. I have finally found an amazing feline only vet that love.
Topically? Really? I would have thought these kind of formulas would be given orally in order to work from the inside out.The good news is homeopathic medicine is what did it! I ordered 3 products from Hampl homeopathics "Anemia Support", "Blood tonic", and "Liver detox". All applied topically.
