Animal Twins
Twins are common in many animal species, such as cats, sheep, ferrets, giant pandas, dogs and deer. The incidence of twinning among cattle is about 1–4%, and research is under way to improve the odds of twinning, which can be more profitable for the breeder if complications can be sidestepped or managed. A female calf that is the twin of a bull becomes partially masculinized and is known as a freemartin.
The nine-banded armadillo (Dasypus novemcinctus) has identical twins (usually four babies) as its regular reproduction and not as exceptional cases.

Famous quotes containing the words animal and/or twins:
“Nobody can misunderstand a boy like his own mother.... Mothers at present can bring children into the world, but this performance is apt to mark the end of their capacities. They can’t even attend to the elementary animal requirements of their offspring. It is quite surprising how many children survive in spite of their mothers.”
—Norman Douglas (1868–1952)
“Sisters we are, yea, twins we be,
Yet deadly feud ‘twixt thee and me;
For from one father are we not,
Thou by old Adam wast begot,
But my arise is from above,”
—Anne Bradstreet (c. 1612–1672)
