New to site (lots of great info) and got my first Ball a couple of months ago. He's 20 in and 155g, about 4 mos old. Pet shop recommend F/T fuzzy mice for feeding and he eats well and regularly (every Friday) except for the first week I had him. (I'm thinking he was just adjusting to his new home). He's taking 2-3 fuzzies, but still seems to be in "hunting mode" after eating so based on his body size and weight I'm going to move to a medium mouse this week. I'd just like for him to feel full after 1 meal versus 3 small ones. My question is: should I move to large mice after he's comfortably taking mediums or move to rat pups? From a lot I have read rats have more nutritional value for the snake. He seems happy and healthy, just want him to get a full belly when he eats. Just got digital scale recently so I don't have any progress charting on his weight gain yet but he seems visably bigger than when I got him. He was smaller than his brother of the same age, but was much more laid back and less skittish so I chose him over his larger sibling. Your thoughts and advice are appreciated. Thanks.
