We got my cat fixed but it still sprays everywhere, why?
Revenge. It's mad at you for getting it fixed. I can't blame it. I'd be mad too.
How old was it when you got it fixed? When an animal is neutered it still has testosterone in it's system. As soon as it "wears off", he should stop spraying.
I have a female that is fixed and still sprays!! It's rather annoying.
