He threw up at 3:00 in the morning last night, mostly wet and a few food chunks, then was fine all day. Then he threw up his dinner in a mass around 6:00pm this evening. Just now, 9:00 pm he threw up some yellowish liquid with a little food remains. It's been raw, wet and old out; the last 2 days were busy stressful but only thing out of the ordinary was a trip to home depot. Help?
