Not sure it works
Both my cats love the taste of these. I give them 3 pea sized servings every morning with their breakfast. However, I have not seen anything pass through normally but instead they seem to be coughing up the hairballs more regularly whereas before, they only do this once every 6 months maybe without the paste..So not sure if it works for my cats but they sure do love it! Not sure if I should continue feeding these to them.
