[3] The Rex has a slightly broader head than other breeds of rabbit, proportionate upright ears, and proportionally smaller feet.
As with most larger breeds, the female (or doe) has a dewlap (a large flap of skin under the chin).
Its origin was a litter of wild gray rabbits[4] and has been developed over the years by fanciers and the fur industry.
The gross external features used to identify the rabbit include weight, coloration, coat texture and length.
The bulk of furs produced in the United States are more of a by-product to the primary purpose of meat production and are of lesser quality.
Meat production favors harvest of young animals (70–84 days) which is not sufficient time for the rabbit to grow a high quality adult fur.
