Pocket pets - companion animals small that we keep contained. Nocturnal = active at night - typically have larger eyes as well (to gather as much light as possible) Crepuscular - active at the day/night transitions - dusk and dawn. Interior is more of a soft, dentin. If lined up, bottom and top will wear each tooth down. Malocclusion = teeth don"t align properly o o o. Causes them to not eat, excessive drooling, can be fatal, open sores. Keep teeth worn down - chew on food, wood. Need a place to hide - stress retreat place. First captured in 1930 from syria - desert region conserve water. Urinate less = odor lowered: hamster - derived from the german word hamstern. Have very large cheek pouches to carry from place to place: don"t feed them soft squishy food - won"t be able to fully extract from pouch. Nocturnal animal from this: undergo periods of hibernation.
