Yes. This is what I do with my life. I stat up giant hamsters in Pathfinder RPG with simple templates.

Cheek Pouch (Ex) A giant hamster can try to stuff a grabbed opponent of two sizes smaller than itself into its cheek pouch by making a successful grapple check. A creature stuffed into the giant hamster’s cheek pouch takes no damage, and can escape by making a successful DC 24 Strength check or can cut its way out by using a light slashing or piercing weapon to deal 14 points of damage to the cheek (AC 12). Once the creature exits, muscular action closes the hole; another trapped opponent must cut its own way out.
A Huge hamster’s cheek can hold 1 Medium, 2 Small, 4 Tiny, or 16 Diminutive or smaller opponents. The check DC is Strength-based.
