Not necessarily. There are small populations of Cheetah that are striped (more like stripy blotches) not spotted. I am not sure whether it is a separate sub-species (the full scientific name is Acinonyx Jubatus Kingii in some writings, which would indicate a difference from the 'normal' Acinonyx Jubatus, but then other writings say it is not a separate sub-species). Anyways it occurs mostly in Souther Africa, and they are quite beautiful. Oh, and they are magic.
Anyways, here are pics of King Cheetahs:
