Cats normally have a thickened area on their lower lip where their upper canine teeth hit it. It is a way for the body to protect the lip. If it appears the same on both sides, this is likely what you are seeing. You didn't mention how old Prim is. If a cat has an abnormal jaw they can have problems with where their upper teeth hit their lower lips, but this will be present from birth and will normally be noticed when they are young. If you think you are seeing something abnormal with Prim, please feel free to post again with a picture, and we will be happy to look at it for you. I hope that was helpful.

    They typically have some bumps to their lips that are normal and not from any trauma from other teeth. If a tooth is loose or malposition it can rub on the gums or lips and cause a sore and some blood. If there is no pain when you touch the area or the tooth and no sores or blood, then it is not likely hitting an area that is causing a problem. If you are unsure or you do notice a sore, then your vet can see if an extraction will be needed
