Amazon.com : Kaolin - Pectin (Kaopectate) - Gallon : Pet Digestive Remedies… I had always liked the real deal with the kaolin and pectin though. Kaolin is a natural earth clay, that has long been used for tummy problems for many various beings. Parrots are known to eat it from cliffs, after having eaten spring fruits that are not fully ripened. It was then sold and changed to the current formula, which is exactly the same as "Pepto Bismol". The active ingredient is bismuth subsalicylate.
