Millie, I think that is a wonderful idea, to pass this information/concern onto Zupreem. Shortly after my post, I was contacted by a shetlter director who informed me that Dr. Gold in Maryland is seeing this issue over and over and is collecting data. I am uncertain at this time what his intentions are regarding collected data. If I am able to discern more information I will share that. I will also look into how we as a united group of ferret owners can best approach Zupreem in a professional manner to encourage some changes in their food formulation.
