Are Anti Rabies Shot Required For A Cat Scratch? Hi!

Are anti rabies shot required for a cat scratch?

Hi! I adopted a street cat last month and we haven't bring it to the veterinarian for injection. A while ago I was getting the garbage inside my room, my cat suddenly became aggressive and she scratched my finger. I immediately called my mom and told her what happened. She told me that we will go to the hospital tomorrow. Do I need to get an anti rabies shots and is it okay to delay going to the hospital from the day my finger has been scratched by my cat?
