Keep in mind that "fat" snakes are not necessarily healthy snakes!! I like the keep my males lean and mean, and really "fat" females don't always produce well (or at all)... Keep 'em healthy and if you are going to bred increase feeding a little before and during the first part of gestation. Often, healthy females will eat less or completely avoid feeding during the latter half of gestation.

Just my 2 cents...
