I'm so happy to hear Beans is acclimating better. I'd have scooped that boy up quick if he was on the East Coast, but I think I have enough M*A*S*H Unit cats now. Does your vet carry "amphoral" by chance? I had a litter of kittens some years back with the worlds worst diarrhea! They had all the routine tests, and meds, and the only thing that worked was the amphoral. Nasty tasting and it has to be given 3 times a day for 3 days. By the second day the babies I had were almost 100% better, and by dose # 9 were good to go. They were covered with poop as was everything else, and it was awful. I waited a week or two after meds and they all went off to new homes. I hope precious Beans starts feeling better soon. Have you thought of adding pumpkin to his food to help bind his stools? Plain 100% with no spices etc. Many cats love it. I'm not going to attempt spelling the active cultures that are in yogurt (acido...) but capsules from a health food store will also help Beans replenish the good bacteria being washed out of his intestines. I hope you can get to "the bottom" of Beans problems, and wish you tons of luck.
