Mini Rex

Rabbit

Mini Rex were derived from the Rex rabbit. Their unique, dense, plush, velvet-like fur, was caused by a mutation seen in wild rabbits in France in the late 19th century. The Rex mutation is recessive and causes the hair to protrude outwards from the body, instead of lying flat, and the guard hairs to be shortened to the length of the undercoat.
