Meadow Jumping Mouse - Young

Young

The newborn young are small, naked, blind, deaf and have no claws. The only thing that these tiny newborns weighing 0.8 grams are able to do is make sounds. After only one week their body begins to get covered with fur and their claws start growing in. Their ear pinnae start to unfold and their hearing begins to develop. Between the first and second week they begin to crawl, and by the third week they are able to hop, and more importantly their hearing has completely developed. Approaching the fourth week their incisors are growing in and by the end of the fourth week they have their adult pelage, and wide open functional eyes. They are weaned and fully independent within twenty-eight to thirty-three days.

Famous quotes containing the word young:

    The world is burdened with young fogies. Old men with ossified minds are easily dealt with. But men who look young, act young and everlastingly harp on the fact that they are young, but who nevertheless think and act with a degree of caution that would be excessive in their grandfathers, are the curse of the world. Their very conservatism is secondhand, and they don’t know what they are conserving.
    Robertson Davies (b. 1913)

    I recently learned something quite interesting about video games. Many young people have developed incredible hand, eye, and brain coordination in playing these games. The air force believes these kids will be our outstanding pilots should they fly our jets.
    Ronald Reagan (b. 1911)

    Cuteness in children is totally an adult perspective. The children themselves are unaware that the quality exists, let alone its desirability, until the reactions of grownups inform them.
    —Leontine Young (20th century)
