Anyway, FortiFlora is suppose to work. But what I do for Red is I give him the cheese from a grilled cheese sandwhich and that kinda helps to solidify it. Although at times that doesn't help either.
Also I feed him Pro Plan canned Turkey and Cheese or Chicken and Cheese (he likes that so he chooses that over the other food thats out), and that seems to be easier on his stomach and the poo isn't totally watery.
If you find a solution please let me know, I'm grasping at straws here. Oh....also Pred does harden up the poops too. But I try to avoid it, though I did give that to him yesterday with pretty good results.
I hope Jonathan gets over this soon.
