As a few others have mentioned, sometimes pieces of kibble would get stuck in the roof of the mouth of one of our ferrets. We use primarily Totally Ferret. So, we now send it through a food processor briefly to break down the pieces into smaller pieces. I do a large batch at a time and store it in airtight plastic deli containers. No more problems with kibble sticking in the roof of the mouth. Jeff In Memory of Neo Caring for Trinny, Morphy, Baby Girl, and Luna [Posted in FML 5863]
