Most cats have short hair, whether they are large or small, wild or domestic. This is an evolutionary development that makes sense for a natural predator relying on stealth and the occasional burst of speed. A hunting cat is more efficient in a short coat because it can glide unhampered through dense terrain and move freely for a lightning pounce in a tight corner.
Short-haired (Group III) - This group includes all cats with short hair, as well as smooth hair and no hair at all. The most numerous group.
