What is a stated purpose of hamster cheek pouches?

• A. Transfer food and bedding from one point to another
• B. Store food in cheek pouches for later use
• C. Aid in digestion
• D. Assist in respiration

Answer: (A)

The idea being tested is that hamster cheek pouches serve as expandable storage that enables the animal to gather and transport food. These pouches act like portable pockets inside the mouth, allowing a hamster to stuff seeds and other edible items and quickly move them back to the nest to eat later. This behavior supports efficient foraging and safe food transport, not digestion or breathing. Bedding isn’t typically stored in these pouches, so the primary function is storing food for later use, with transport to the nest as needed.
