My shakespeare had the same thing a week ago. I gave him dry food when I left and he was eating it. Whem I came back there is vomit all over the place. I was like ahhhhh
what happened??!!?? Then I smelled all of them because we have three and I found out it was shakes. He was cold and not very active. so I rush him to the vet and did some blood and fecal test and found out that he has pancreatitis and had to leave him there for a couple of days for IV treatment. I was worried the whole time but the vet said he will be fine. So I took his advice.... He is back now and happy as can be. So I think your furbie will be okay too.
