Just been trying to order some Cystease S for my girl who's suffered from cystitis in the past. This product has been discontinued and replaced with Cystease Advanced with contains other ingredients other than the usual N-Acetyl Glucosamine. Just wondering if anyone has tried this yet and if their cats were okay from the point of view of side effects. My girl will be on Cystease (or Cystaid) for life.
