I don't even think that the yogurt is helping him. This morning there weren't any messes on the carpet but when I came home this evening I smelled something. Starr had pooped on his placemat and it's back to diarrhea again. There was some more in the litterboxes so I guess that by adding some new litter it's helped him use the boxes. I gave him a little more yogurt and some more bene-bac. He actually likes the bene-bac. I think I'll call my vet tomorrow to let them know what's going on. I also e-mailed Nancy but I haven't heard a reply yet. I've also noticed that when Starr has diarrhea that he doesn't eat as well. I think that his tummy may be hurting him. I'm ready to go ahead and try a new diet. Hopefully something will work.
