The Field mouse has been proven to be extremely intelligent. If given time, it will think out a strategy before doing something. They have extremely small but sharp claws, which they use to dig into houses to scavenge food. They assess a situation before doing anything. They will judge whether it is too risky, dangerous or useless and they often look out for each other. However, if they are being chased, they will dart undercover or into small nooks and crannies.
