I'd never heard of FIP before Warren got the dreaded diagnosis. Two different vets told me that euthanasia was the humane thing to do, but I had already lost two other cats to other causes in the previous year and couldn't believe that Warry was going to die, too, before he was even a year old. I happened to mention this to a friend, who happened to have heard of FIP Warriors from one of her friends. Thanks to that double-coincidence, I satisfied myself that this wasn't a Nigerian prince scheme and ordered a 10-day supply of GS pills. By the time they arrived, Warren was within days at most of death. The turnaround was dramatic -- I could see improvement after the second dose, and he was on the way to recovery by the time my trial ended. Needless to say, I followed the whole regimen, and he's been cured for a year now.
