hi, I really think you are mistaken about bringing up the stools, this sounds to me very much like hairballs...these hairballs take the long cylinder shape of the bowel they were lodged in and appear dark and smelly much like a stool. stop giving her all the products...especially any sugar, sugar is really bad for cats. a tiny bit of Oliver Oil or plain Yogurt is ok. cats do not necessarily have a bowel movement every single day...I think you just need to stop the products and keep an eye on her for a few days, I really do not believe she is constipated...right now she is vomiting from all the stuff you have been giving her
