Part One:
Many folks have questions about the difference between a Highland Lynx cat, the Highlander and an ordinary domestic cat. Here is some Highland Lynx information that may help to answer those sorts of questions.
To define and explain their differences I would begin with their history and origin. In 1995 the first Highland Lynx kittens were born at Timberline Cattery in N.C., a result of a cross between Desert Lynx cats and Jungle Curl Cats. Desert Lynx cats are believed by some to have originally have been hybrids of domestic cat breeds (such as Maine Coon or American Bobtail) and a wild bobcat, (though according to science this does not appear to be possible). The Jungle Curl cats are a hybrid mix of domestic curled ear cats (such as the Hemingway Curl or possibly the American Curl) with the African Jungle cat (Found in Egypt, Asia, India, etc).
The Highlander Cat was originally the same cat as the Highland Lynx, but is now a separate breed. The Highlander is also of domestic origins, mainly breeds such as the Desert Lynx and Highland Lynx. The goal was to produce a domestic cat with the look of a big cat and to seek competition/show status in registries such as TICA (The International Cat Association).
