Rosella, please keep us posted re Noni, Popeye (love that name) and Elsa as would be so interested in something working for this bleddy disease. I can testify to probiotic really helping cats's guts as mine managed to keep free from antibiotics for over a year using probiotic and thus was able to finally shed that tritrichomonas foetus bug that he must have been born with by dosing him with it every single day. He had years of squits and illness previously before it was diagnosed and kept having antibiotics every year of his life since kittenhood because of gut problems until we found out that they actually stop the cat shedding the tritrichomonas. Touch wood he's been squit free for several years now with the antibiotic poweder, which I never thought I'd see. Luckily I've got a marvellous vet who approved of my not putting him through the drug therapy, which was pretty traumatic.
