caprine (adjective; KAP-rin): of, relating to, or resembling goats.
Caprine shares the same root as “caper” (to prance about, frisk, gambol) which is Latin for, of course, goat. “Capricorn” gets in on the etymological action, too.
These are angora goat kids, from a delightful website: Crookabeck Farms. They’re a farm in the English Lake District–Beatrix Potter country–that raises exotic fiber animals, apparently.
