Hey guys. I usually buy Tidus the same food over and ovaer again. But lately the company (I'm sure I can't remember the name) introduced a new formula with Fish Oil in it. Well I tried it and in the last 3-5 days Tidus has had diarrhea. There are solid stools sometimes but most of the times it's not solid. I seacrhed my house and backyard to see if he was eating something strange but I couldn't find anything? I'm gonna say it is the new formula with fish-oil, and ask: What should I do? Will he get over this eventually, or should I just see if I can buy his regular food before this new stuff?
