www.imulan.com (print for your vet to help get your cat treatment quicker) Two of my cats are Positive for these viruses. They started the new cutting edge natural treatment called LTCI by IMULAN. My cats simply get the natural injection under the skin every so often and get blood tests once in a while to keep an eye on their progress. So far so good! Some cats treated in the study had new blood tests done and they turned negative. I will defintely update if my cats are blessed with negative results. I put this on you tube for many people and even vets have no idea that this treatment is available. It is approved in the US. If your cat is positive, you might want to consider LTCI.
