Hi everyone. I don't come on the forum very often anymore, but I wanted to share what I have found with my cats' food. I have two cats, one who had FIV when he was born (passed along in utero from his FIV-positive mother). Long story short, I entered him into an experimental study when he was a kitten and he no longer has FIV. He is now a happy old boy, living WAY past his original life expectancy. So yay! However, through all of that treatment, he was on A LOT of antibiotics. Since then, his digestion has been compromised and he would frequently vomit after eating.
