Thanks again everyone. He seems to like his new food but it's a litter bit crunchier than his old food so it makes it a little harder for him to eat. I'm supposed to mix in some of his old food with it for 3-5 days so I really won't know much until he's on the new food exclusively.

Yesterday was a good day with no accidents but sometime between 8-10am this morning he pooped all over the place again. It was mushy poo but not black and tarry looking like before so it looked more normal. I had just cleaned out all of the litterboxes at around 7:45am so they weren't dirty. I just don't know if some of this is still due to behavioral problems or health related. Nancy e-mailed me and she'll be talking to Starr in a few days. I hope he's able to let her know what's going on.

I've also noticed that when I give Starr the bene-bac that he seems much better the next day. When I gave it to him 2 days in a row though, this is when he had the black tarry stools so it may have been related to this. I know it may take some time for his system to get under control so I'm trying to stay positive about this new food. Thanks again.
