She has a small black lump or bump on her head. It doesn't seem to hurt her when I touch it or look at it.
Lumps could be abscesses or tumors. Most abscesses get broken when they reach a certain size.
If your cat does act normally and has no problem eating and drinking, it doesn't seem to be urgent. Follow the growth of the lump and if it starts growing, if you notice that it is causing pain to your cat, or if it doesn't disappear in approx. one week, you should take her to your veterinarian to examine the lump and determine the cause so it doesn't cause problems to your cat.
All the best for you and Hazel.
