Black Cat on the Road is a long term quest. You will finish it when you lift Bastet's curse. To do this, you have to complete all the quests that you will receive from Bastet and her Priest. Keep working on the main quest line and you will get there soon.
You need to find a new quest, a little help:
What is the last finished location?
What does your quests menu show?
We need these info to can help you. (We, helpers in the forum, are players just like you. And we don't see your game.)
