I got my snake June 6th and it weighed 90.7 grams. I have given it 3 small live mice since then and today it still weighs 90.7 grams. It has not went to the bathroom yet since I got it either. It shed last week. It seems healthy. It also seems to like to be held. Should I be concerned?

Also I don’t have a clue if my snake is male or female. I got my snake at a swap meet and hopefully the next one (July 11) the guy remembers who I am and will be able to tell me if it’s a male or female.
