I was given a 4/5 week old grey squirrel. He was healthy and active had been fed wiskers cat premix 4 m. I changed him to Ebola’s yesterday as it seemed by reading to be better for him. He ate every 3 hours as previous and seemed fine til 6 am he acts like he can move back legs . He took his 3/4m of milk but has runny diarrhea. I have dumor electolight, the cats milk from previous, and milk replacer. Any advise
