1st of all...welcome!

As for the stool, zoe has been getting diarrhea on and off for a few months. I'm sure its something they ate that we don't see. They have very sensitive stomachs. Since the stool test came out negative then I would switch him to the chicken and rice diet. boiled white chicken breast with rice and water so that its bland and goes down smoothly. After a few days of this his stool should go back to normal. Remember to slowly switch back to his regular food after his stool hardens.

it also wouldn't hurt to give him a little bit of yogurt for good bacteria.

Hope this helps.
