hey /an/ i usually just browse but i am worried about my cat, shes nearly a year old now and not spayed.

and i was giving her a belly rub today and i noticed a bump the size of a marble. then i inspected a little closer and its on one of her nipples. im a new cat owner so should i be worried because i dont really know what i should do about this.

do i go to a vet or not worry because its cat breasts.

maybe its some small infection too but i will still see a vet as well.

i just need an informed opinion if its possible.
