The "regurge" is about 6 in long and an inch wide and very mucous-y. The white doesn't look like the uric acid stones that usually accompany his poops. Is it okay for him to not have solid stools? The second picture is definitely not solid at all and is not like his normal poops. I'm also concerned that it's been a week since I fed him and for him just now to regurgitate his food...isn't this abnormal?
