Moon Cat

Moon Cats are a curious species of felines native to the Earth's moon.

Biology
Physically, they look like an exotic kind of cat, with long thin bodies, almost serpentine in shape, and long legs that make them resemble cheetahs. Like Earth cats, they make a purring sound when they're content. Like all moon creatures, they live for centuries.

Culture and society
Although they don't participate in the Council that organizes the lives of plants and animals and ensures that none is preyed by others; the Moon Cats respect the "no killing" rules and have evolved away from their predatory instincts and learned to survive on other sources of nourishment. These haven't been specified, although it's been demonstrated that they enjoy milk.
