i am very happy to hear that your cat heal! My cat only eats raw meats, so I was thinking that maybe if your cat eats only meats and organs for a few months her immunity will get stronger and she'll be able to fight the virus on her own. Grains will put so much pressure in her digestive tract that, in my opinion, the healing will be slower. in any case, I do hope she gets completely better.
My grandma has been stable. I am traveling to my home country at the end of the month, and i'll be taking with me a bunch of herbs and supplement to help her improve. I am ordering the herbs from mount rose today but just realized that they only sell the aerial parts of the sheep sorrel herb. in the link you sent, she recommends the whole plant though. I am ordering anyways and will put all my faith into it. Did you noticed this when you order the herbs?.
