What does it mean when a chipmunk gently bites your hand?

1. If there is salt or moisture on the hands of the breeder, the chipmunk will lick it clean by gently biting the hand. Breeders need to keep their hands clean and avoid licking their hands frequently.

2. Branch rats will drag their favorite things into their nests, which is a way to express friendship.

3. It may be that you hold the rat in your hand and it feels uncomfortable, so it nibbles to remind you to put it down.
