Sigil for summoning a familiar which is a symbiotic being in the form of a cat with many snake-tails.

It can be humanoid if you want. Symbiotic means this is a spirit who will be joined with your soul and thereby expand your awareness somewhat, adding their personality to your own.

(I am aware this sigil may have other uses, but with the intent of summoning the symbiotic snakepussy it will work.)
