Controlling the size of your BP

[youbeyouibei]

If you feed them properly, no, you cannot "guarantee" that a snake will stay a certain size.

The only way possibly would be if you were to starve it. And you shouldn't own animals of any kind if you even THINK of doing that.

If you get a snake, be prepared on the fact that it can get LARGER than average.

x2 to this ^. You could try and handpick one that has "smaller" parents; genetics would factor into that but again, no guarantee of an animal staying a certain size. What's your concern with one being longer/larger? I have a few large females who are over three feet and several thousand grams and they're as docile as my 149 gram juvenile. If you're intimidated by their size, maybe they're not the species for you. Not trying to be harsh, just saying.
