The difference between British Shorthair cats and ordinary orange cats mainly lies in their breed and appearance. First of all, the two cats are completely different breeds. The face and eyes of British Shorthair cats will be rounder, and they will also have cheeks and ears. The limbs are shorter and the body is more rounded; while the face of an ordinary orange cat is like a normal cat, with pointed eyes, almond-shaped eyes, pointed ears, slender limbs, and a thin body.
