Royal Ball Python Upsizing Meal Part 1

Royal Ball Python Upsizing Meal: (Frozen/ thawed)
It is time to upsize Samara Morrigan's meal from mice to rat! By my mistake her rat is at 40g when it should be 30g! I have been monitoring her to make sure she doesn't regurgitate. Sometimes being new to something, which I am a new Ball Python keeper, we can make mistakes.
