Hamsters stuff their faces with food into a seemingly endless pit, but finally we have answers as to how far that pit goes. A new documentary series on BBC One, Pet - Wild at Heart, asks the tough questions about the rodent's eating habits. Using an X-ray camera, the show reveals exactly what happens when those cute hamsters start mashing treats into their cheeks. The video claims that hamsters don't secrete saliva while stuffing their cheek pouches with food so that it stays fresh and dry, while the X-ray footage shows that the pouches actually extend all the way to the critter's hips. The two-part series premiers Wednesday, Jan. 21 on BBC One.
