Shaving The 🐱

I'm almost 15 years old and I've been shaving since I was 12/13 and I shave my 🐱 every week or two but every time I do, I always cut myself. I do not know how to prevent that. It always hurts, too. I try and go slow but I always end up cutting myself. Then I have to wait a minute before shaving it again so I don't make a deeper cut. Any advice? 😭
