A striped leopard is a contradiction in terms, but Nature is full of contradictions. One is the striped/blotched King Cheetah, originally thought to have been a distinct species, now known as a recurring genetic abnormality. There is a similar abnormality, which, in handful of even rarer cases (one writer says about a dozen are known), produces this amazing striped leopard.
A lovely creature, isn't it?
