I'm pretty sure pumpkin is recommended for constipation, not loose bowels. I gave it to my cat and it worked, briefly, until he decided he hated pumpkin and I couldn't fake him out. This would mean that you are overstimulating his bowel, rather than calming it down, and as a result he constantly has the urge to go without being able to produce anything. And since he has no other weird symptoms, I'm guessing he's fine.
