It does not work. I believe in magick, I'm not a stern practical nerd, but it isn't realistic - not even in Wicca or Paganism - and it doesn't work. There is no way to transform into a Neko wolf based on the spell. Of course, the creator of this website warned us that people will submit their fantasy spells joking around, not knowing the true meaning of Wicca, but it's up to us as the independent, wise individual to discard all fantasy and keep true magick in our mind.
I am sorry, darling, but it doesn't work that way with magick, unfortunately. If we could reform ourselves physically, we'd always be something different than what we were born being.
