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:
“Man is the only animal that laughs or weeps; for he is the only animal that is struck with the difference between what things are, and what they ought to be. We weep at what thwarts or exceeds our desires in serious matters; we laugh at what only disappoints our expectations in trifles.”
—William Hazlitt (1778–1830)
“Celestial Cupid her fam’d son advanc’t,
Holds his dear Psyche sweet intranc’t
After her wandring labours long,
Till free consent the gods among
Make her his eternal Bride,
And from her fair unspotted side
Two blissful twins are to be born,
Youth and Joy; so Jove hath sworn,”
—John Milton (1608–1674)
