Additive

Sugar (added sugars)

controversial

Added sugar in any form; one of the most important categories to avoid in ferret food and treats.

Why it's debated: Ferrets' pancreas evolved for steady glucose from protein metabolism, not dietary sugar spikes; chronic sugar exposure drives beta-cell hyperplasia and insulinoma. Hidden sources include honey, molasses, maple syrup, fruit juices, and dried fruits.
