Cure Benson of FIP

We adopted this kitty and found out a month later he had FIP. (feline infectious peritonitis) We decided to treat him with Mutian and all went well until he finished his last day of treatment. His blood work was amazing so we were so disappointed. Within 3 days, he showed that he was relapsing. He had lost all the weight he had gained and was not eating. So we decided to research a little more and see what we could do to save him. We adopted sweet Benson to help cheer up my two boys. We are going through a rough home situation and my oldest has some health and now serious anxiety issues. So for many reasons, we need to save Benson. We paid for the initial round ourselves. Mutian could not guarantee it unfortunately like they have now. Mutian said we could try 450 mg per day for 4 weeks and see how he does. He is such a good kitty around my kids. I appreciate any help!!
