| Mice sleep during the day and are active at night. Our mice are housed on reversed 12 hour light/dark cycle so that their active period coincides with our active period. We use red lights to see them during their "night time.". This picture was taken around 9:00 AM, Just as the white lights in the animal room are going out and the animals are waking up. |

|
The mice are quite active and enjoy hangining from the tops of their
cages. |

| When awake, the
mice spend most of
their time on their running wheels. Notice that the mouse on
the right is in not blurry at all. The mouse on the wheel is
blurry, not because of the camera, but because the mouse is moving so
quickly. If you look closely you can see two left eyes, but
the legs are just a blur. |

| Every
cage of mice has one of these igloos. Although we can see
through
them, the mice are unable to, and thus feel safe "hiding"
inside.
Note the pin sticking out of the top. |

| The pin on top of the
igloos can be
used to add a running wheel so the mice can get their
exercise.
The mice love runing on the wheels. |


| This pup is returning to the igloo after briefly steeping out to explore. The picture has been made black and white in order to filter out the red light. |

| We caught this pup out of bed (and out of the igloo). The pups now have fur and have grown quite a bit. They're rapidly approaching the size of the grownups. |
