First Nekos are make believe creatures anime i believe. You fck not change your DNA cannot morph or become anything.
And I agree with the eye color comment you can not change your DNA.
And changing tempt just look at the basics.
You cannot turn yourself into anything other than human. Magick can do no more than nature can do itself for we take the energy from it along with ourselves to cast our spells no? Just so you can understand, you cannot turn yourself into a cat. You cannot change your DNA because that could not be able to happen in nature. I don't know enough about Cyrokinesis to tell you if it's real or not, but I do connect with the elements. You cannot give yourself angel wings or a tail. It's just plain not possible. I hope you understand what I'm saying.
