I agree about the acidopholis (probiotics are great!) One thing we would do and it really does help if you can get them to eat it, is peel and core an apple, then grate it, then spread it out on a plate and let it turn brown. If you can get them to eat the browned shredded apple it helps. There is some chemical that devolops in apples when they turn brown that helps diarrhea.
