I'd think the idea that no BP could become "obese" and have health complications based via overfeeding would be naive, no? The simple answer would be no, but that's often in comparison to other relatable species like burms which are prone to being overfed. Overfeeding with BPs would typically refer to oversized prey rather than quantity of meals. But yea, you'd be hard pressed to find someone who can successful throw rodent after rodent in every other day and have their BP take them down and pass them on the regular without issue.
