A 120-day-old Rex rabbit usually weighs about 4 kg, and a large individual can reach more than 5 kg. The common rex rabbit of the same age weighs only 3-3.5 kg. In terms of appearance, French Rex rabbits have wider front shoulders, almost as wide as the rear hips, and the whole body seems to be rectangular; while other Rex rabbits have narrower front shoulders, and their bodies are long triangles with wide back and front narrow. In addition, the plush of the French Rex Rabbit is short and dense, and the skin is not exposed in the wind.
