Hi! I have been using Sweet PDZ on my poop boards for years now and love it. However, last time I went to get some, the feed store said they no longer carry it. I have gotten the same story at the other stores near me. I am using sand now, but it just isn't the same. Had anyone tried Santi-Care or Chick Flik? These are the two things that seem close. Any other suggestions for me? Thanks!!!
