Oh, poor you and poor Kacey.

It's a long shot - if something is blocking his digestion, would it be worth it trying a small dose of lactulose or even olive oil to see if that would help move things? Or some pepcid to coat his tummy, it might help his appetite?

I am so sorry to hear this...and that 'what's wrong' can't be pinpointed.

HUGE PT Prayers for Kacey.
