1911 Encyclopædia Britannica/Eyra

EYRA (Felis eyra), a South American wild cat, of weasel-like build, and uniform coloration, varying in different individuals from reddish-yellow to chestnut. It is found in Brazil, Guiana and Paraguay, and extends its range to the Rio del Norte, but is rare north of the isthmus of Panama. Little is known of its habits in a wild state, beyond the fact that it is a forest-dweller, active in movement and fierce in disposition. Several have been exhibited in the London Zoological Gardens, and some have grown gentle in captivity. Don Felix de Azara wrote of one which he kept on a chain that it was “as gentle and playful as any kitten could be.” The name is sometimes applied to the jaguarondi.
