I give them a banana chip or a raisin about once every two weeks, but then I found out that other people in the house hold were sneaking them more than that. I put two water bottles in the cage because I know diarrhea with any living creature can cause dehydration, and he does go through about one and half a day. I asked our vet about the bene-bac and he said that he had some, because I couldn't find any stores around us that carried it; he said to come by and pick it up when ever. Within a day or so of calling him, but when I checked his poo they were normal, my mom picked up the bene-bac already and I'm going it to him anyways just to be safe.
