As of 4pm, the cPLI results had not come back in. The liver enzymes were normal. Today I took him back in, he's still not eating and he had a very mucousy poop today (like with colitits). The vet did an abd. x ray just to rule out obstruction, his fecal is negative. She stared him on Flagyl, Reglan and canned i/d until we can figure things out. He ate 1/2 the can! He's now in better spirits and resting. No more Pepcid since it really didn't help him. Hopefully, he can tolerate it and keep it down.
Thank you everyone for your help
