Sebaceous Cysts

Yellow has had 5 or 10 of these, each one does it's own thing. There are three kinds. On the skin, under the skin and today's - the first that has erupted. 

They come to the surface and sometimes they appear like mini cauliflower, kind of bumpy and maybe with a little scab-but tiny.

Today's was a puss filled erupting bloody mess. 

The vet saw a photo and confirmed that I should clean it, trim her fur and that in a few days it should heal up.
