Nope, no aspirin there. I don't know about the efficacy of kaopectate, but I would tend to expect that it's true the bismuth in the pepto bismul is an important ingredient in certain diseases like ulcers -- I don't know about in the green diarrhea. You probably wouldn't be able to use pepto 2-3 or more times a day if it had aspirin -- I believe ferrets are pretty sensitive. So since I know ferret vets who use it that often, I'm sure it's perfectly safe, although some don't like it for ulcers `cause it tends to turn stools black and it's hard to tell if the ulcers are resolving since that's a major sign.
