I use my 3,000 gram female mentioned earlier as a garbage disposal. She has eaten jumbo rats, 300 grams plus, several times. She never regurges and never has trouble digest. I wouldn't do it every week, but it's never hurt her. Balls aren't true red tail boas or emerald trees that are prone to regurge. Do you really think a wild Ball would pass up a meal that size? Not trying to argue, this is just my experience.
