Maybe his food? My little Gizmo who will be 6 mo's this Sunday also had very bad runny stool last night , but I think it is because he ate some of the cats food and it has salomon and other stuff and maybe it irritated his tummy.... so I gave him 1/2 a cc of pepto and 1/2 a cc of some medicine my vet gave me to clean his system. Hopefully he is better. I have him eating Wellness and he seems to like it... since he is so small 2 1/2 lbs at his age I have to be very careful. try to check his food.. Good luck and keep us posted. Thanks!
