I was scratched by my cat last night. (She is an indoor cat and has been vaccinated). The scratch isn't very deep and I cleaned it with soap and put neosporin on it, but now I'm really freaked out and scared that I'm going to get tetanus, because I heard that you can. I haven't had a tetanus shot in 13 years and I'm not really wanting to get another. Do you think I should be worried about tetanus from a cat scratch?
