You know how hamsters dig in their cage lining material? Pawing through it? Creating a nest to settle in? I call this 'hamstering' or a need 'to hamster'. These are cricetine habits. Example: "We always wait for her to hamster for a few minutes before we start on a road trip: purse positioned just so, nail file and dental floss handy, water drinker settled in place, hand projects within reach, and seatbelt fastened, with the lambswool cushion pad positioned for comfort at her shoulder." Hamstering.
