Chipmunk:

Chipmunks are small, striped rodents related to squirrels. They are active during the day and spend much of their time foraging for seeds, nuts, fruits, and insects. Chipmunks store food in cheek pouches to bring back to their burrows, which may have multiple entrances and chambers for sleeping and storage. While generally beneficial for seed dispersal, chipmunks can become pests by digging in gardens or raiding bird feeders.
