I have a ball python i got about a month agao and it was supposed to be 2 months old when i got him. My question is i weighed about a wek after I fot him and he was 66 grams and two weeks later he was 88 grams. Then today I weighed him and he is 76 grams. Every week since I got him he has taken a live mouse hopper with no problem. Is it normal for the weight to be this low and also change up and down like that? The temps and husbandry are good and he shows no signs of being sick at all. Hes just skinny. lol
