There are many varieties of neko (cat people) on the grid: striped, spotted, furry, smooth-skinned...One of the rarer alternatives (to date only seen on Vortex "Koen" Koencamp and his mother Sumalee) is the Bloodtail neko of Sumatra.

Bloodtails are distinguished by ebony fur in a striped pattern, with blood-red paws, ears and tail. It is not known if this is just a familial variation, as no other examples have been seen on the grid.
