Our eight month old kitten started throwing up hairballs two months ago and we used the malt jam and dry hairball cat food. If we didn't find a hairball one day we would fine two the next day. We eat oatmeal most every morning so I started to give her one tablespoon every morning. You guess it. No more hairballs. I'm sure that the oatmeal has cured her hairball problem. Give me your feed back.
