As some of you know, I'm trying to get to grips with my cat's cystitis bit by bit. I'm about to try her on a higher quality diet (ie more meat) and have been looking closely at all the ingredients in Bozita, Purely (Pets @ Home), Natures menu, Feline Fayre, HiLife, Applaws and Almo. Some of them state they contain tapioca starch, eggs, sunflower or soy bean oil, sugars or vegetable extract. Bearing in mind I'm trying to avoid anything that might irritate her bladder, does anyone have any views on these ingredients? My first choice at the moment is Pets at Home Purely, but that contains tapioca starch. Has anyone tried any of these and did their cat like it?
