So, I had my snake for about 5 or 6 feedings so far. I feed him 1 prey item every 7 days. My snake is about 40 inches long. I would feed him 1 small adult mouse or 1 rat pup per feeding. This is his first feeding that he decided to not eat. He was not interested in eatting at all. I have switched from mice to rats and he doesnt care what is infront of him. He also just shed about 4 days ago (first shed with me) and i htought for sure he would eat. He never even thinks twice, once the mouse is near him he demolishes it. So after he didnt eat it after a few mins i took the mouse out. I will try a rat in a few days and see if thats what he wants. Its just upsetting when they dont eat.
