Well.... you made the commitment to own a snake and you should not be afraid of it getting to big. Balls can get up to 5 feet and if you don't want it to grow to big i suggest you give it away or sell it because a snakes gotta eat just like a human and starving it for 2 weeks almost will make it more aggressive (possibly) and it will probably lose weight and become sick and die and i know no one wants that.
