Thanks. It is definitely not dirt. The patch has been slowly getting bigger. She is behaving normally - eating socializing, not vomiting. She does not go outside. We’ll take her to the vet tomorrow.
If anyone else has any ideas, please keep the comments coming.
Within the last 4-5 days my cat’s upper lip has turned dark in color. I’m not noticing excessively licking but it is basically in the area where she would lick her lips. The first picture is for comparison. The second one was taken today.
