I just did a Yahoo search on the Chausie, and here is the description by a website, as to what a Chausie is:
When people get their first glimpse of a Chausie â€“ especially one striding along in slinky, liquid motion â€“ their first encounter with these magnificent creatures rarely fails to create an indelible impression. One is immediately struck with the feral grace and agility of this svelte, muscular cat. All cats are graceful animals, but there is an extra measure of it evident in the Chausieâ€™s every movement â€“ an extra helping of that pure, essence of â€œcat-nessâ€ which makes our feline friends such intriguing companions.
With long legs and a lean, powerful body, the Chausie [pronounced â€œchow'-seeâ€] is a highly active and athletic cat; one which manages to keep busy in all manner of mischief. Chausies are almost dog-like in their eagerness for nonstop play and their deep devotion to their owners.
THE CHAUSIE MYSTIQUE ... A 4,000 YEAR LEGACY:
The Jungle Cat was found in ancient Egypt and was accorded sacred status in the time of the Pharaohs, perhaps for their role in helping to keep rats from infesting grain supplies. In fact, it is the tall, slender, elegant physique of the Jungle Cat that is immortalized in the Egyptian feline statues which honor the goddess Bastet. Some Jungle Cats were trained by Egyptian royalty to hunt wild water fowl. Others were entombed with the Pharaohs to be their companions in the afterlife.
The name â€œChausieâ€ was derived from the Latin name for the breedâ€™s wild ancestor, the Jungle Cat, which is felis chaus. Since the objective of Chausie breeders is to develop a new breed of cat that retains the appearance and superior intelligence of the Jungle Cat, but has a fully domestic temperament, it helps to know something about the Jungle Cat.
â€œJungle Catâ€ is such a generic-sounding term, many assume it refers to any wild cat whose habitat is the jungle, such as a Leopard, Jaguar or Ocelot. But the Jungle Cat is a distinct species and one of the largest among the smaller wild cats, weighing from 20 to 40 pounds. The Jungle Cat is the widest ranging and among the most populous species of all wild cats today. It can be found from North Africa across the Middle East into southeast Asia. It ranges north into Soviet Asia and south into the Indian subcontinent. Contrary to its name, much of the Jungle Catâ€™s habitat in these various regions is desert or arid mountain terrain.
CHAUSIE BREED HISTORY:
Jungle Cat hybrids, were the first Chausies and were bred as early as the late 1960s and early 70s. The gentleman who started the breed that is known today as the Chausie no longer breeds and has not been heard from recently.
Chausies were and are a breeding between a Jungle Cat and a domestic shorthaired cat. Early Jungle Cat hybrids were bred to offer those interested in exotic cats a more reasonable alternative to the often ill-fated attempts to make a pet out of a wild animal.
In general, the domestic cats used in these early hybrid efforts were often selected at random. Today, however, with the Chausie Breed Standard in mind (see "Breed Description" link below), the domestic crosses used by our Breed Group are carefully chosen for an appearance as close as possible to the Jungle Cat.
Chausies gained foundation registry status with TICA [The International Cat Association] in 1995. More recently, in February 2001, the breed was advanced to Evaluation status, meaning that, as of May 2001, Chausies have been eligible for evaluation at the benching areas of the show hall. Championship status, nonetheless, is most likely several years away.
I would say the cat you are thinking of purchasing, would NOT be a Chausie, since there is nothing in them that is supposed to be bred with a Bengal.
