They have been bred in many different colors. This is a wool breed, and will require extensive daily grooming and a special diet. This is a short rabbit with well-developed shoulders and hindquarters. The head is held high and close to the shoulders. The ears sit high on the head and then flop down to 1/2 to 1 inch below the jaw. The show standard requires the wool to be slightly coarse, very dense and equal in length throughout the body. The American Fuzzy Lop is shown in six different groups based on its color pattern: broken, pointed white, wide band, agouti, shaded, and self. Within these groups, the agouti colors of chestnut, chinchilla, opal, and lynx can be seen. A number of other colors are also available in this short and stocky breed.

Size: Under 2.5 pounds. The Britannia Petite is an old English breed known in UK as "Polish". It is generally thought to have been developed from small, common rabbits. The breed is currently recognized as the smallest of the standard breeds. In the United states, the Britannia Petite is commonly recognized as being white with red eyes, although they are bred in many color varieties in Britain. These tiny, compact rabbits have relatively narrow heads and a trim, arched body line. Ears are medium long and erect. Experienced rabbit breeders have claimed these rabbits have a tendency to be more hyper and nip more often than other breeds, and that they require especially careful handling because of the delicate arched body type. The show standard requires the head to be wedge-shaped and broad across the forehead. The neck is short, and erect ears are in contact with each other for their full length. The Britannia's fur is sleek and silky. This breed is known to be curious , alert and is suitable for older children who can handle this light-statured breed gently.

This breed is growing in popularity as a pet and show rabbit because of its luxurious coat. Rex coats have guard hairs which are fine, straight, and no longer than the underhairs, resulting in a plush coat that looks and feels somewhat like velvet. The Mini Rex rabbits have been bred in many colors. The breed was developed using the standard size rex. Weighing about 4 pounds, the Mini Rex is available in the same color varieties as its larger cousin, the Rex. Foot disease is more common in rabbits with Rex fur because of the lack of the heavy protective fur on the foot pad. (Photo credit: March Hares Rabbitry )
