Why is my hamster stuffing bedding into her pouches?

Hamsters often stuff bedding into their cheek pouches as a natural behavior to create a cozy nest or to hoard materials for later use. This instinctual action helps them gather resources in the wild, where they might need to transport bedding or food. If your hamster is doing this, it’s likely a sign that she feels comfortable in her environment and is engaging in normal nesting behavior. Just ensure she has enough space and appropriate materials for her to express this behavior safely.
