My cat digged her claw in my leg's skin it's a small scratch i immediately desinfected it and washed it but it got me worried as it felt deep, it stopped bleeding after seconds, do i risk an infection? its an indoor cat?

Don't be too fearful: While some risk is unavoidable, the most important thing to do is keep the wound very clean, as you have done. Keep a close eye on the wound. It may feel without any problem. Signs of infection are increasing pain, redness swelling and heat. Seek help if these occur. Unnecessary use of antibiotics can promote development of dangerous resistant infections. I hope this helps.
